->''"The only danger ''[of space travel]'' is if they send us to that terrible Franchise/PlanetOfTheApes. Wait a minute... Statue of Liberty... '''that was our planet!"'''''
-->-- '''Homer Simpson''', ''WesternAnimation/TheSimpsons''.

At some point of a SpeculativeFiction story ([[DownerEnding often the end]]), the apparently alien setting turns out to be none other than UsefulNotes/{{Earth}}, [[AfterTheEnd warped and twisted by disaster, disease, the passage of time, or some other instrument of drastic change]].

Almost invariably this involves a character who was sure he was anywhere but Earth discovering the AwfulTruth, after finding TheConstant.

At some point, this actually was very shocking (partially because humanity was [[TruthInTelevision very close to blowing itself up]] in the 1960s) and is one of the most famous kinds of TwistEnding. Through over-use, these days, it's become TheUntwist; it would usually be more surprising if the apocalyptic planet turned out to be anywhere ''but'' Earth.

* A classic ''Series/TheTwilightZone'' twist: the characters in the story turn out to be HumanAliens. They're stranded on a primitive planet and now have to colonize. On resigning themselves to their fate, the leader says, "And I shall call this planet 'Earth'." [[AdamAndEvePlot Double points if his name is Adam.]] (The original ''[[Series/TheTwilightZone Twilight Zone]]'' actually used this plot in "[[Recap/TheTwilightZoneS5E129Probe7OverAndOut Probe 7--Over and Out]]".) According to [[Wiki/{{Wikipedia}} The Other Wiki]], this one's known as the [[http://en.wikipedia.org/wiki/Shaggy_God_story Shaggy God story]] and was overused to the point of being a DiscreditedTrope as early as the 60's.
* The preferred ''Series/TheOuterLimits1963'' version: the peaceful folks living in fear of alien invasion are really humanoid aliens. The aggressors? Humans. - this variation also a classic ''[[Series/TheTwilightZone Twilight Zone]]'' episode- "[[Recap/TheTwilightZoneS2E51TheInvaders The Invaders]]".
* Instead of believing it to be a different place, believe it to be a different time. You believe you're in caveman days, but later realize you're in the future AfterTheEnd, or you believe you're in the future, but later realize you're in the [[{{Precursors}} past during an enlightened period]] that will later get destroyed (with all record of it also wiped out).

As you might expect, this is an '''[[AC:EndingTrope]]''', so there are many '''spoilers''' below. However, once you've read the description above, most Earths All Along are self-spoiling anyhow.

Compare AdvancedAncientHumans, when there was a technologically advanced human civilization in ancient times; and EarthThatWas and EarthThatUsedToBeBetter when Earth was lost, destroyed, or fell on hard times long ago. See also HumansThroughAlienEyes and TomatoSurprise.

'''Caution: There will be spoilers!!'''



[[AC:It Was Earth All Along]]

[[folder:Anime and Manga]]
* The last few episodes of ''Anime/BrigadoonMarinAndMelan'' indicate that Brigadoon, which had appeared to be a different world, is Earth in the distant future.
* In ''[[Anime/{{Xabungle}} Combat Mecha Xabungle]]'', the low-tech worker-caste "Civilians" scrape out a hard-scrabble existence on a desert world, believing themselves to be descended from Terran colonists; over the course of the series, the planet is revealed to be (of course) Earth, stretched to the very end of its ecological rope. The 'colony' story was spread by the high-tech ruling-caste "Innocents" [[spoiler:to cover up their plans to escape off-world and leave the Civilians to die.]]
* In ''Anime/EurekaSeven'', it turns out that the planet everyone escaped to to get away from the aliens invading Earth is actually Earth itself, transformed by the [[StarfishAliens scub coral]] into a mostly-unrecognizable shape.
* The 2003 anime of ''Anime/FullmetalAlchemist'' [[spoiler:reveals that it is set in an AlternateHistory of Earth, which also exists as we know it in a parallel universe. The two worlds were the same until their histories diverged when alchemy worked in one and didn't in the other, splitting them into two separate dimensions.]]
* In ''Anime/GargantiaOnTheVerdurousPlanet'', this is the FirstEpisodeSpoiler -- Ledo has rediscovered EarthThatWas, and the ice age that caused his ancestors to abandon it has ended, making it a [[SingleBiomePlanet water planet]]. The rest of the series is him adjusting to the situation.
* ''Anime/MacrossDoYouRememberLove'', when Hikaru and Misa find out that the planet they were transported to is Earth after a Zentradi attack.
* There are sufficient hints at the end of ''Anime/MaiOtome'' to make the viewer at least wonder if the apparent colony world is in fact a far-future and much-changed Earth.
* Yasuhiro Yoshiura's ''Anime/PaleCocoon'' inverts this. [[spoiler:It was the ''Moon'' all along. People thought they were living under destroyed Earth, and lost most of their historical records, but actually they were living in a Moon-colony with artificial gravity where people escaped environmental destruction. And when the protagonist looks at the sky for the first time, he sees blue Earth shining in the sky, as a sign that the planet has healed long ago, but no-one had thought to look.]]
* ''Manga/{{Psyren}}'', Volume 01 Chapter 005/006: The strange unnatural world that Ageha finds after being transported by a magical telephone call (no, really) is none other than a devastated Japan, as revealed by the crater-scarred face of Mt. Fuji.
* Parodied in ''Manga/SgtFrog'': Giroro and Natsumi get warped into a Desert of the Real by accident, and while searching for signs of civilisation, find it in the form of a familiar landmark in the series, the NPG Radio Tower - in ruins. [[spoiler:The untwist: they're NOT in the distant future, the tower was merely declared obsolete after the NPG company built a better one. And there's several other previously obsoleted towers in the immediate area, just to hammer the point home.]]
* Inverted in ''Anime/SoltyRei'', where the people were made to believe that they were on Earth after a major disaster, but turn out to be colonists on another planet [[spoiler:after a major disaster cut the colonization process drastically short]].
* ''{{Manga/Toriko}}'' Chapter 259 reveals that the Earth the characters live on ''is'' Earth, with much, much more territory added on by a mysterious mineral.
* Clow Country in ''Manga/TsubasaReservoirChronicle'' is the Tokyo from the Tokyo/X arc, just at a different point in time. This also counts as NiceJobBreakingItHero since the protagonists were at least partially responsible for what happened to it.
* ''Anime/{{Vandread}}'' the robotic aliens that pest the protagonists for most of the story turn out to be drones sent from Earth to [[spoiler:''harvest'' living organs]].

[[folder:Comic Books]]
* In a bizarre case of this trope (it was not the end of the series, but CliffHanger revelation for the issue), ''ComicBook/ArchieComicsSonicTheHedgehog'' series had Mobius revealed to be Earth far into the future, after an attempt by Cthulhu-like aliens to [[ApocalypseHow wipe out humanity for crimes against them]]. This was done to make the comic fall in line with [[Franchise/SonicTheHedgehog its video game brethren]], which had Sonic and company on Earth from the get-go. Some fans were not amused.
* In the ''Magazine/DoctorWhoMagazine'' comic ''The Glorious Dead'', the Doctor discovers that the planet Dhakan is in fact Earth with an altered history, after the discovery of St. Paul's Cathedral.
* ''ComicBook/TheGreatPowerOfChninkel'': A "before the origins" variation. The planet Daar is in fact Earth around a billion years ago. After [[{{God}} O'ne]] destroys almost all life out of spite for not being worshipped, life re-develops over the course of millions of years and the last Tawals (an ape-like race who barely survived the previous destruction) eventually become modern humans.

[[folder:Fan Fiction]]
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** In ''FanFic/TheWritingOnTheWall'', the titular writing on the wall was left behind by humans, who built the ruins that Daring Do was exploring. They were a warning not to disturb them, and with good reason.
*** [[spoiler:"You should not have come here. This is not a place of honor. No great deed is commemorated here. Nothing of value is here. What is here is dangerous and repulsive. We considered ourselves a powerful culture. We harnessed the hidden fire, and used it for our own purposes. Then we saw the fire could burn within living things, unnoticed until it destroyed them. And we were afraid. We built great tombs to hold the fire for one hundred thousand years, after which it would no longer kill. If this place is opened, the fire will not be isolated from the world, and we will have failed to protect you. Leave this place and never come back."]]
** In ''[[https://www.fimfiction.net/story/239715/ruin-value Ruin Value,]]'' Celestia wanders through the ruins of a destroyed city after the world has been ruined by magic. It turns out that the city was, in fact, a human city, and while it was AfterTheEnd, it was actually set long before ''WesternAnimation/MyLittlePonyFriendshipIsMagic''.
** In ''FanFic/DiariesOfAMadman'', thanks to DramaticIrony the reader finds out early on that Equestria is actually set on a version of Earth far into the future after humanity is ([[LastOfHisKind mostly]]) extinct, but it takes some time before the human protagonist finds this out for himself.
** ''Fanfic/TheLastHumanATaleOfThePreClassicalEra'' is a FusionFic of Literature/TheLastUnicorn and ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', but it's eventually revealed [[spoiler: Equestria is a fusion of post-apocalyptic Earth and Ponyland from the G1 cartoon ''WesternAnimation/MyLittlePonyAndFriends''.]]

[[folder:Film -- Animated]]
* ''Animation/FantasticPlanet''. The titular planet turns out to be this.
* Shua spends much of ''Animation/SkyBlue'' talking about how great Gibraltar will be, and how he'll go there after the fall of Ecoban. Guess where Ecoban is.

[[folder:Film -- Live-Action]]
* [[InvertedTrope Inverted]] in ''Film/DarkCity'', where the City is assumed to be located on Earth for much of the film, but TheReveal shows that it's actually an simulated environment in space.
* The Czech science fiction film ''Ikarie XB-1'' (released in the US as ''Voyage to the End of the Universe'') actually gained one of these through CutAndPasteTranslation; in the original film, the characters were human astronauts seeking "The Green Planet"; the [[CulturalTranslation Americanized]] version of the film added [[spoiler: stock footage of New York City to the scene where they finally discover the planet]], changing the ending from [[spoiler:TheEndOfTheBeginning]] to Earth All Along.
* Parodied in the mockumentary ''The Independent'' starring Jerry Stiller: one of the films Morty Fineman creates is entitled ''What Planet is This (Oh My God it's Earth)''.
* In TheFilmOfTheBook ''Film/LogansRun'', Logan and Jessica make it to the surface only to find the ruins of Washington, D.C. In the book, it was made very clear where they were to begin with -- Washington was not in ruins; it was not AfterTheEnd, but just in a Brave New World-like pleasure culture. This is why they wind up safe not on Earth but on a space station orbiting Mars.
* Combined with BreakingTheFourthWall in the Soviet film ''Per Aspera ad Astra''. The plot revolves around helping the planet Dessa to recover from a self-inflicted ecological disaster. In the end the film stops being sci-fi and becomes surrealistic, then ends with the note "All images of the dying world Dessa were filmed on Earth".
* The original film ''Film/PlanetOfTheApes1968'' ends with the revelation that protagonist George Taylor is back home, which comes when he comes across the ruins of the Statue of Liberty, which acts as TheConstant. ([[Film/PlanetOfTheApes2001 The 2001 remake]], while treading the same ground, uses a quite different ending based on that of [[Literature/PlanetOfTheApes the original French SF novel]]; in the novel, one crewmember manages to return to Earth, but discovers that the Ape takeover also happened to Earth in the meantime, and takes off again.)
%%* Similarly inverted in ''The Signal (2014)''
* {{Parodied}} in ''Film/{{Spaceballs}}''. Spaceball One/Megamaid is blown up, and the head and arms fall on the Planet of the Apes, resembling the Statue of Liberty. The implication, of course, is that maybe it wasn't really Earth all along after all.
-->'''Ape:''' [[PrecisionFStrike Oh shit]]. There goes the planet.
* ''Film/TheVillage'' appears to be set in a rural 19th century village. Beyond the woods surrounding the village, however, is present-day America; the village was founded by people who wanted to recreate 19th century society, and their children don't know what year it really is.
* ''World Without End'', the first sci-fi movie filmed in Technicolor [=CinemaScope=], told the story of a group of astronauts on a space mission who crash land on an unknown, Earth-like planet. They know it can't be Earth because there are no radio signals and the radiation count is too high. They learn the truth when they encounter a graveyard. In an interview, the film's director Ed Bernds said, "If anybody could sue anybody, I could sue Rod Serling for ''Planet of the Apes'', because they definitely used my ideas about space travel and time travel in making that picture."

* ''...And All the Stars a Stage'', by James Blish, makes an interesting use of this trope. The protagonists escape their Doomed Homeworld just before their sun (a big blue-white one) goes nova, and wander the Galaxy looking for a replacement. Two previous tries turn out to be deathtraps, and just as they are running out of time and hope and everything, they stumble across a system with a little pipsqueak yellow star and decide it's their last chance. Yeah. [[spoiler:The twist on the twist is that they arrive in Predynastic Egypt and just miss the coronation of "Earth's first king". It is very strongly implied that the survivors fade quietly into the human population.]]
* Creator/MarkLawrence's ''Literature/TheBrokenEmpire'' series starts out seeming like your typical gritty medieval fantasy setting, until you realize there's quite a lot in common with our own world, such as famous philosophers and holy figures and other hints sprinkled here and there, all building up to some very obvious implications more than halfway through the first book that all but outright tell the reader that the setting takes place in a post-apocalyptic Europe an uncertain number of centuries after a nuclear holocaust.
* In ''Literature/TheCityOfEmber'', the city turns out to be ''underground'' on Earth. Human beings lived there for centuries; the idea was to protect them from nuclear war, but they lost the evacuation instructions years ago, and no one was around to tell them that the apocalypse was over and they could all go home now.
* In Christian Cantrell's "Containment", the protagonist lives in a colony on Venus, and is trying to solve various environmental problems [[spoiler: but it turns out the colony is actually on an apocalyptic wasteland Earth, and the problems he has been assigned are actually to make money for the colony / control the air supply]].
* ''Literature/DespoilersOfTheGoldenEmpire'' lives on this trope. It presents itself as a science fiction story about a military expedition to another planet, and is written in very scientific-sounding prose, but the story is actually about our planet only. Bonus Points for it being not just a fictional tale set on Earth, but a highly accurate (if deliberately misleading) account of an historical event that actually happened (the conquest of Peru by Spaniards in 1500s). In this case, it is only the reader who is fooled; the characters in the story all know full well what planet they're on. Hints are given to this fact throughout the story, though:
--> The sun, a yellow G-O star, hung hotly just above the towering mountains to the east.
* "Series/DoctorWho And The Hell Planet", a short story by Terrence Dicks in which the titular Hell Planet (full of volcanoes and dinos) turns out to be prehistoric Earth. ''The Completely Useless Encyclopedia'' [[DeadpanSnarker acerbically]] suggests it would have been a much better surprise to reveal it ''wasn't'' prehistoric Earth.
* Another Creator/LarryNiven example comes from his ''Literature/DracoTavern'' stories: the chirpsithtra remember a civilization they met millions of years ago, whose planet was undergoing geological upheaval, and a green blight was taking over the oceans, converting much of their atmosphere into oxygen. This killed them off in the end, but created the conditions necessary for us and (almost) everything else we know.
* Ea of David Zindell's ''Literature/EaCycle'' turns out to be Earth millions of years into the future.
* The children's novel ''Galax-Arena'' by Gillian Rubinstein is about children who are abducted by a man named Hythe and seemingly taken to another planet and forced to perform high risk acrobatics as entertainment for aliens. This scenario turns out to be a ruse designed to quash all hope of escape; the "alien" spectators are humans in disguise, the "planet" is a secret facility in the desert and the children are not entertainment, but lab rats.
* ''Literature/TheHelmsmanSaga''[='s=] first books contained some references and allusions implying it occurs in the very distant future. Then, in Book 8, the protagonist's ship is lost, and his EscapePod lands on Earth in the 60s.
* ''Literature/TheHomewardBounders'' is a slight subversion: instead of planets, you get Homes. Still an absolutely unexpected TearJerker.
* The short story ''The Hunters'' has an invasion by ferocious aliens who destroy the civilization of the planet. At the end it is revealed that the invaders are humans.
* In ''Literature/TheInvertedWorld'', the city which is apparently TrappedInAnotherWorld turns out to have been on Earth all along.
* An odd variation in H. Beam Piperís ''Lord Kalvan of Otherwhen''. Hero Calvin Morrison assumes that heís been thrust forward in time to a post-apocalyptic Earth, until he sees the outline of a familiar mountain range, and realizes it shows no sign of strip-mining. Since the amount of erosion necessary to eliminate the evidence of manís work would also make the mountainís silhouette unrecognizable, this makes him realize that he must be in a parallel universe instead.
* "Merlin's Gun" by Creator/AlastairReynolds has a variation: it is obvious to the reader that part of the story takes place in our (long-abandoned) solar system, but the characters never realise where they are.
* ''The Nitrogen Fix'' by Creator/HalClement kicks this up a notch by making Earth ''actively uninhabitable'' to human beings (as in, survival domes and oxygen masks), and introducing an alien race that thrives in the new environment.
* In Creator/JRRTolkien's unfinished story ''The Notion Club Papers'', a man learns to astrally project himself and so visit distant alien planets. After describing several of them, he then came across a world where he watched what looked like a teeming anthill spread disgustingly across a verdant countryside. He then realised it was Earth All Along, and he was watching a sped-up history of his own hometown of Oxford.
* In Creator/MichaelMarshallSmith's typically {{Mind Screw}}y debut novel, ''Only Forward'', The City was mistaken by the protagonist for a parallel dimension but turns out to be a future Earth. TheConstant here is Nelson's Column.
* Subverted in ''The Psalms of Isaak''. The world the series takes place in is AfterTheEnd, heavily uses {{magitek}} (some bits of which are recognizable analogues to present-day technology), and is heavily implied to be Earth. The fourth book reveals that the planet's name is Lasthome, and it's actually a LostColony of a spacefaring human civilization, presumably from Earth.
* In Grant Naylor's ''Literature/RedDwarf'' novels (not the TV series), Lister is trapped on Garbage World, where humanity has dumped centuries' worth of its waste, for 30+ years. Early on, he finds the oil- and acid-rain-soaked, but still recognisable, shape of Mount Rushmore with its five presidents' heads (don't ask).
* ''Literature/TheSearchForWondla'', [[spoiler:Though if you squint, Rovender ''does'' give some foreshadowing. Also, [[FridgeHorror the water bears.]]]]
* Surprisingly, ''Literature/SeptimusHeap''. In one of the final scenes of the final book, ''Fyre'', Septimus writes the current date on the snow outside the House of Foryx. It reads: ''July 4, 12,004''.
** Implied earlier on, when they reference the few remaining technological miracles from the "Days of Beyond", which you can guess are supposed to be the present/not-as-far future.
* ''The Shattered Sea Trilogy'' (by Joe Abercrombie of ''Literature/TheFirstLaw'' fame]]) takes place in a Viking-like society which is actually in the far future Baltic Sea after a nuclear war, where Finland appears to have sunk. The fist clues are the geography matching too well, the names of elf ruins being corrupted versions of present day cities, and a tribeswoman wearing a circuit board as an amulet.
* In Creator/AndreNorton's ''Star Rangers'', a decrepit patrol ship from a decaying human-dominated [[TheEmpire galactic empire]] finally breaks down for good far from the galactic core and its civilizations. The faraway fringe world on which our heroes are stranded seems almost too perfect to the human crew members, though...
* Inverted in ''Literature/TerminalWorld'', another Creator/AlastairReynolds novel. The world is always referred to as Earth, but a museum (with a panorama of [[{{Heavyworlder}} strangely short men]] in clumsy space suits) and a crashed ship in the Bane reveals that the world is a terraformed Mars.
%%* Gary Paulsen's SF novel ''Literature/TheTransallSaga''.
* A variation: Creator/LarryNiven's ''A World Out Of Time'' has a [[YearInsideHourOutside relativistic]] spaceship pilot trying to return to Earth millions of years after he set out, and since [[spoiler:the solar system has undergone extensive remodeling since he left]] and his computer has gone crazy, he can't ''tell'' whether it's Earth or not. And since the launching system he needs to get back up to ramscoop speed is long gone, he has to figure out which is true before he stops-- because once he does, he can't go anywhere ever again.

[[folder:Live-Action TV]]
* ''Series/DoctorWho'': [[Recap/DoctorWhoS23E1TheMysteriousPlanet "The Mysterious Planet"]] features the discovery (due to a Tube sign) that the planet the Doctor and Peri are on is actually Earth, after it had been shoved halfway across the galaxy.
* In ''Series/TheOuterLimits1995'' episode "The Light Brigade", the crew of a stricken ship must launch a [[DoomsdayDevice Doomsday weapon]] on an enemy planet in order to save humanity. However, in one of the {{Cruel Twist Ending}}s the revival series became infamous for, [[spoiler: the aliens had tricked the crew into believing that that they were in orbit above the enemy planet, when in actuality they were above Earth, and our heroes end up nuking our own planet.]]
* In the ''Franchise/MetalHeroes'' series ''Series/JikuuSenshiSpielban'', it is revealed that the planet Klin, the once-beautiful now-ravaged home of our protagonists, is Earth in the future, and they were sent to Earth through time rather than space.
* ''Series/StargateSG1'', "Solitudes": Two members of the team seem to have been shunted to the wrong planet due to an overloaded Stargate. Turns out it's a second Earth gate, buried under the ice in [[MysteriousAntarctica Antarctica]]. This also serves as a great big {{lampshade|Hanging}} for the whole SingleBiomePlanet thing.
* Played with in a fascinating way in the original StarTrek series, where the Enterprise encounters multiple duplicates of Earth that had apparently been duplicated at specific points in history. The specific case of the world of the Yangs and Kohms in "The Omega Glory" is mentioned below, but "Miri" and "Bread and Circuses" also feature similar planets. (Probably involved the Q Continuum, but they never really made a point of establishing where they came from onscreen.)
* ''Series/TheTwilightZone'' episode "[[Recap/TheTwilightZoneS1E15IShotAnArrowIntoTheAir I Shot an Arrow Into the Air]]" features 3 astronauts crash landing on what they think is an unknown desert planet. At the end, it is revealed that the "desert planet" is actually [[spoiler: a stretch of Nevadan desert about 97 miles from Reno. Only one astronaut survives the infighting over water and supplies to discover this]].

* Appears in the MusicVideo for "Sing For Absolution" by Muse. After flying a spaceship across the galaxy, Matt Bellamy and his crew collide with an asteroid and plunge onto a desolate desert planet. They step out... and find themselves on the ruins of Westminster Bridge, London, with the smoking remains of the Houses of Parliament behind them.
* A kitschy Leonard Nimoy track called "Visit to a Sad Planet" ends with an unsurprising revelation.

* The ''AudioPlay/BigFinishDoctorWho'' audio drama "Terror Firma" has the reveal that the setting of the story is a Dalek-conquered Earth.
* A hybridization of this trope, the AdamAndEvePlot, and an ''anti-''Earth All Along occurs in the '70s BBC RadioDrama ''Radio/{{Earthsearch}}'': The crew of the colony-ship ''Challenger'' tries to return to their home planet, Earth, to find it missing, and finally decides to settle on the new planet Paradise. Paradise is a lot like Earth, but it has saltwater oceans, and a heavily cratered moon. They eventually start referring to the planet as "their" Earth. There are a number of clues and red herrings -- the other planets in Earth's solar system have different names, but we're told that the planets were renamed centuries earlier, for example. Just in case you didn't work out the original "Earth" wasn't Earth at all, the sequel begins with a global flood.
** The {{prequel}}, ''Earthsearch: Mindwarp'' takes place in an underground complex thought to be surrounded by rock infinitely in all directions, but when the main characters escape they find themselves on the original "Earth", but this happens early on.
* The ending of the first season of ''Radio/TheHitchhikersGuideToTheGalaxy'' radio series, as well as ''Literature/TheRestaurantAtTheEndOfTheUniverse'' in its novelization adaptation, features the main characters unexpectedly once more on Earth, with a rather unflattering secret about mankind unveiled in the process. [[spoiler:We're apparently descended from a race of aliens who're all TooDumbToLive.]]

[[folder:Tabletop Games]]
* A similar case is with the ''TabletopGame/DungeonsAndDragons'' setting of ''TabletopGame/{{Mystara}}''.The [[http://pandius.com/master-outer-world-colour.png global map of Mystara]] bears a suspicious resemblance to that of [[http://geomaps.wr.usgs.gov/parks/pltec/sc152ma.html Earth 152 million years ago.]] (It also features a solar system with an additional planet instead of an asteroid belt. A planet named ''[[MeaningfulName Damocles]]''...)
* The Roleplaying Game ''TabletopGame/{{Earthdawn}}'' has a metagame aspect of this trope: the setting takes place A Long Time Ago on Earth, but there is no time travel, and the inhabitants naturally aren't affected by this. However, the clues were few (with only very small maps available), so most players actually never figured it out.
** Note, by the way, that the RPG ''TabletopGame/{{Shadowrun}}'' is in contrast one of the most successful [=RPGs=] on the market, while being the same universe as ''{{Earthdawn}}'', just TwentyMinutesIntoTheFuture rather than a long time ago.
** If by "very small" you mean "obviously shows Crimea, the Black Sea and the Caucasus" (e.g. a good chunk of southern Russia and Ukraine).

[[folder:Video Games]]
* ''VideoGame/CityOfHeroes'' has a weird version of this: much of the game's plot revolves around an alien invasion from a world in a parallel dimension. [[spoiler:Which turns out to be an alternate version of Earth, where humans have been heavily modified into killing machines.]]
* ''VideoGame/DokaponKingdom'': Parodied by LetsPlay/TheRunawayGuys, when they check out the map to see that the game map looks similar to Earth.
-->'''LetsPlay/{{Chuggaaconroy}}:''' It was our world all along! FRIENDSHIP IS RUINED FOREVER!!!\\
'''LetsPlay/ProtonJon:''' ...Okay.
* In ''VideoGame/{{Drakengard}}'' 's bonus ending, Caim and his dragon chase the queen beast into another dimension, but that dimension happens to be modern-day Tokyo. It's still an alien dimension to Caim, and this is illustrated by the fact that Tokyo is entirely in black and white.
* The ending of ''VideoGame/IllusionOfGaia'' reveals that the game took place on Earth all along, but just the the cause of evolution had been altered by Dark Gaia.
* The first ''VideoGame/{{Pikmin}}'' game suggests this, and the second one confirms it. The third game has an interesting twist: it's indeed Earth, but it looks like Pangea Ultima (which is what the Earth is assumed to look like 250 million years in the future).
* In ''VideoGame/{{Splatoon}}'', it's revealed in one of the Sunken Scrolls that the world the Inklings and Octarians are fighting over is actually a post-apocalyptic Earth. 12,000 years ago, the sea levels rose dramatically and the human race was pushed to extinction. Marine invertebrates evolved and reclaimed the land, building their cities over the ruins of the old human ones. [[spoiler:They even uncover a fossil skeleton of a human being. [[TakeThatAudience Which just so happens]] [[http://i.imgur.com/b1HUyAn.jpg to still be clutching a Wii U.]]]]
* ''VideoGame/SuperRobotWarsUX'': The game reveals that the moon contains a Tokyo from the previous universe.
* ''VideoGame/XCOM2'': [[spoiler:In the final mission, you assault an alien base using a portal you previously stole from them. At first it is implied that the base is located on an entirely different planet, but it later turns out that it's actually on Earth, at the bottom of an ocean. ]]

[[folder:Web Comics]]
* This is reversed in ''[[http://www.dawnoftimecomics.com/index.php Dawn of Time]]''. At first it appears to take place in the past, with the addition of the [[ArtisticLicensePaleontology cavegirl-alongside-dinosaurs]] Flintstones device. However, as more of the world is shown through the story it's revealed that there are large cities, more advanced technology, and trading routes, showing that the world is more of an alternate universe. It's just Dawn who's incredibly primitive [[spoiler: and possibly not even human.]]
* Double-subverted by ''Webcomic/{{Homestuck}}''. On [[http://www.mspaintadventures.com/?s=6&p=007034 this page]], we are shown the [[spoiler: Cherub]] world, which has the Statue of Liberty (in crappy jpeg form, no less). The view then zooms out, revealing ''several'' identical Statues of Liberty, leading many readers to suspect that it isn't actually Earth. Then Andrew Hussie's AuthorAvatar tells [[spoiler:Caliborn]] outright that the planet is Earth--specifically the Earth from the Alpha timeline, moved into the new universe by at-the-time unknown means. Hussie even lampshades the use of the Statue of Liberty:
-->Weren't all the Statues of Liberty a dead giveaway? \\
If you see one or more shitty old Statues of Liberty on any post-apocalyptic wasteland planet, that automatically means it was Earth all along, as a rule. \\
Then when you realize that, you're supposed to have a mental breakdown.
* Inverted in [[http://nedroid.com/2007/03/beartato-107/ this]] ''Webcomic/{{Nedroid}}'' strip, where the setting is suddenly revealed to be Mars. [[spoiler: Subverted later, where it's revealed that Reginald just has "[[MemeticMutation brain problems]]" and hallucinated the whole thing.]]

[[folder:Western Animation]]
* Lampshaded in ''{{WesternAnimation/Futurama}}'': "The next day, Billy's planet was destroyed by aliens. Have you guessed the name of Billy's planet? It was Earth! [[FantasticAesop Don't date robots]]!"
** Then turned UpToEleven in a season seven episode, where, 6,990 years into the future, humans, apes, birds, cows, and a slug-like race have all rose to power, destroyed themselves, and then subsequently conquered the weakened race.
*** And each one making its own Statue of Liberty. Right next to the others.
* In the ''WesternAnimation/JusticeLeague'' episode "Hereafter" Superman wakes on a planet with a red sun after being blasted by Toyman and presumed dead. He makes his way across the wasteland to a jungle area, dealing with strange local creatures along the way. Considering the page this is on, you can guess what he learns when he meets up with his old 'friend' Comicbook/VandalSavage.
* Parodied in ''WesternAnimation/TheMask'' when he and Peggie find themselves on a planet inhabited by pigs. They find the ruins of the Coco Bongo.
-->'''Mask''': "It was Earth all along, [[LampshadeHanging don't you get it?]]"
** Made even funnier by how they all call the planet Earth throughout the episode, and the title itself is "When pigs ruled the Earth".
* In addition to the Homer quote above, ''WesternAnimation/TheSimpsons'' episode "A Fish Called Selma" includes a musical [[ShowWithinAShow stage version]] of ''Franchise/PlanetOfTheApes'' called "Stop the Planet of the Apes, I Want to Get Off". The song that Troy [=McClure=], as Taylor, performs during the final scene literally names the trope in its lyrics:
-->''I hate every ape I see\\
From chimpan-A to chimpan-Zee\\
No, you'll never make a monkey out of me!\\
Oh, my God! I was wrong!\\
It was Earth All Along!\\
You've finally made a monkey,\\
(Yes, we finally made a monkey!)\\
Yes, you've finally made a monkey\\
Out of me!''\\
'''I love you, Dr. Zaius!'''
* The punchline of the first season of ''Franchise/{{Transformers}}: WesternAnimation/BeastWars'' was that it ''doubles'' as both a sequel '''and''' prequel to ''WesternAnimation/TheTransformers'': the primitive planet on which they found themselves was, indeed, Earth all along, millions of years in the past, and the entire series was set during the period of dormancy while the Autobots and Decepticons were unconscious in their crashed ships halfway through the first episode. However, all the characters were from long after the original series, winding up on prehistoric Earth due to time travel. There are some dead giveaways ([[spoiler:Stonehenge was made by aliens!]]), but enough red herrings to make them look like they aren't dead giveaways. [[spoiler:Speaking of red herrings, the second moon turns out to not be a moon at all.]] TheReveal is handled nicely, bringing the plot together for second and third seasons with episodes far more connected than those of the first.
** Particularly well handled considering that Megatron believes it is Earth from the first episode, though Dinobot does not, given the two moons and lack of civilization. Audiences were given conflicting evidence to support either a primitive Earth or an Earth-look-alike until discs came into play.
** Hell, the ''writers'' [[SchrodingersGun weren't sure if the planet was going to be Earth or not when they started]]; they basically figured "Throw in a second moon and if we finally decide this is Earth, we'll [[DetonationMoon blow it up.]]"


[[AC:It Was Our Homeworld All Along]]

[[folder:Anime and Manga]]
* The 2011 ''Anime/DragonBallZ'' special ''Episode of Bardock'' shows that Goku's father Bardock survived his death at the hands of Freeza and was somehow blasted back into the distant past, waking up on Planet Vegeta back when it was called Planet Plant (and before it was inhabited by either the Saiyans or their enemies the Tsufuru). In addition to discovering that the ancient Plantians invented the liquid used in Freeza's {{Healing Vat}}s, [[spoiler:Bardock battles Freeza's ancestor Chilled and goes Super Saiyan, meaning ''he's'' the legendary Super Saiyan that drove Freeza to kill off the Saiyans.]] The [[WebVideo/DragonBallAbridged Abridged]] version had a RunningGag where Bardock is on the verge of figuring out this incredibly obvious plot twist, only for something to interrupt and derail his train of thought -- and when he finally gets it, his anger at how stupid it is is what triggers his Super Saiyan transformation.
* In ''Manga/MahouSenseiNegima'' [[spoiler:the magical world is in another dimension, but metaphysically tied into Mars. Remember how Chao said she was from Mars?]]

[[folder:Comic Books]]
* The ''ComicBook/{{Elseworld}}'' mini-series/graphic novel ''ComicBook/SupermanRedSon'' ends with a twist: Krypton is actually a far future Earth, a utopia created by Jor-L's famous ancestor Lex Luthor, who founded it [[StableTimeLoop after defeating]] the Comrade of Steel (see TemporalParadox).

[[folder:Film -- Live-Action]]
* ''Film/{{Pandorum}}'': The audience is led to believe [[spoiler: the spaceship has been drifting in space, but it is revealed at the very end that they had crash landed on the destination planet hundreds of years ago. If they had ejected themselves and the rest of the passengers at the beginning, they would have been saved.]]

* The ''Magazine/TwoThousandAD'' short story ''The Last Hurrah of the Platinum Horde'', by Creator/AlanMoore, has a gang of space age barbarian warriors deciding to leave their home planet and set off in a straight line across the universe raping, pillaging and killing everything in their path. It turns out that the universe is curved, and they end up coming back to their homeworld from the opposite direction and inadvertently sacking it.
* Done in the 1968 ''Captain Future'' novel ''Planets in Peril'' by Creator/EdmondHamilton. The protagonist goes to help a human looking race in a dying universe (a short time away from being reborn in a new Big Bang), impersonating an ancient hero of that race. In the end, it is revealed that the universe is actually our own some 20 billion years in the future. What was the ancient hero's name? '''Kaffr'''!
* The early Creator/ArthurCClarke short story "Encounter in the Dawn" depicts FirstContact between a technologically advanced galaxy-spanning empire and a primitive caveman tribe on a backwater planet. The description of the explorers is humans in the StandardSciFiSetting, however when the survey team is recalled, it is revealed that the cavemen they interacted with would eventually found the city of Babylon.
* In ''Literature/ThePendragonAdventure'''s eighth book, ''The Pilgrims of Rayne'', Ibara is revealed to be an island on Veelox a few miles off the shore of Rubic City. 300 years in the future. Upon visiting Rubic City, Bobby finds the place a ghost town, with the [[LotusEaterMachine Lifelight Pyramids]] now being tombs, and the only humans around are crazed pirate-like scavengers. It's rather terrifying.
* Creator/IsaacAsimov's ''Literature/TheStarsLikeDust'' is a veritable cornucopia. About half the chapters end with the reader's sudden discovery that the story's location is not what it seemed. Contains examples of "It Was Earth All Along", "It Was The Homeworld All Along", and "After The End".
* An award-winning ''Franchise/StarTrek'' short story called "Our Million-Year Mission" had an ''Uber-Enterprise'' ([[spoiler:comprised completely of holograms from the galaxy's best minds, including the crews of all the ''Enterprises''...and a very real Data; no one but him knows any of that until TheReveal, however]]) that finds a replica of the Milky Way galaxy devoid of life billions of light-years from where it should be. [[spoiler:Only it's not a replica...it ''is'' the Milky Way, and all of its life-forms have ascended to a higher plane of existence, making it a sentient ''galaxy''.]]

[[folder:Live-Action TV]]
* The twist ending to the fifth season premiere of ''Series/{{Andromeda}}'' was that the dystopian Seefra-1 was really Tarn Vedra, the captain's home planet and former seat of the Commonwealth.

[[folder:Tabletop Games]]
* ''TabletopGame/MagicTheGathering'': [[WordOfGod Mark Rosewater]] says the initial planning for the ''Mirrodin Besieged'' block would have had the first set be ''New Phyrexia'' (rather than that being the last set in the block), with clues to eventually reveal that the plane they were on was Mirrodin. Instead they decided to chronicle the plane turning into New Phyrexia, and do a marketing HopeSpot that perhaps the last set in the block would be "Mirrodin Pure".
* In the Hollow World inside TabletopGame/{{Mystara}}, sections of doomed surface-world civilizations have been transplanted and preserved by the Immortals. Most such cultures traditionally believed that their patron Immortals actually ''rebuilt'' their native worlds to protect them, rather than re-located them en masse; however, the recent arrival of surface-world explorers and traders has proven to many that they'd been moved to the planet's interior.

[[folder:Video Games]]
* ''VideoGame/DragonQuestIII'' (''Dragon Warrior III'' in America) had the protagonist fall into the Dark World, where he must defeat the demonlord Zoma. After defeating him, the locals celebrate by giving him the title of Loto (or Erdrick, in American NES versions). This reveals that the "Dark World" is actually Alefgard, the kingdom the first game takes place in (which also appears in the second), and that III was a prequel (though anyone who played both games would likely come to this conclusion almost as soon as they arrived there, what with the almost identical geography and town names). This game also plays with the trope in the first part, as the main world of [=DQ3=] is modeled after Earth itself.
* A variation occurs in ''VideoGame/{{Iji}}'' in that while the setting is on Earth, the enemy alien invaders realize that Earth was ''their'' birth planet (which they call Origin). But they don't realize this until ''after'' they hit it with an AlphaStrike.
* ''VideoGame/JakIIRenegade''; upon discovering the ruins of Samos's house partway through the game, Jak says, "This horrible place... is our world!"
* ''Zork Zero'', prequel to the seminal ''VideoGame/{{Zork}}'' text adventures, makes its setting in the timeline fairly clear from the start. The twist comes at the end of the game, when you inadvertently transform the castle in the story into [[spoiler: the little white house from the opening of the original game]].

[[folder:Western Animation]]
* In ''WesternAnimation/StarVsTheForcesOfEvil'', Ludo realizes after ninety days stranded on a seemingly random planet that he's been in the wilderness of Mewni all along.


[[AC:Starting Earth from Scratch]]

[[folder:Anime and Manga]]
* ''Anime/GallForce: Eternal Story'' had a variation where the MacGuffin world being fought over was a {{terraform|ing}}ed version of Earth's moon. The story ends with the moon left lifeless and [[AdamAndEvePlot two of the cast stranded on a prehistoric Earth]].

[[folder:Comic Books]]
* A [[UsefulNotes/TheSilverAgeOfComicBooks Silver Age]] ''Franchise/{{Superman}}'' story (which hasn't been in continuity for decades), "A Name Is Born", had two astronauts from other worlds land on prehistoric Krypton, fight, save each other's lives, and get stranded. Naturally, when they took off their helmets, one was male and the other was female -- and they were named Kryp and Tonn.

[[folder:Film -- Live-Action]]
* ''Film/TheHitchhikersGuideToTheGalaxy'' film ends with the rebuilt Earth coming to life.
* In a popular ''[[Series/MysteryScienceTheater3000 MST3K]]'' episode, ''Film/WomenOfThePrehistoricPlanet'', the captain of the ship leaves his illegitimate daughter Linda behind on said planet with NatureHero Tang, the son of the survivors of the ship they were trying to rescue. He accepts that they'll be happier together on their new world, then pronounces (in the cheesiest way possible), "The third planet will henceforth be known as... 'Earth'."

* ''Literature/TheRestaurantAtTheEndOfTheUniverse'' dumps Arthur on a ship transporting Golgafrinchans, HumanAliens who perform useless jobs towards a mass genocide. They land on a beautiful planet, settle it, and set about ruining it with their bureaucratic and stupid ways of performing basic tasks. Arthur realises that the Golgafrinchans were the ancestors of humans, not the ape-like beings native to Earth. However, the book ends with Arthur sitting by a stream, watching the trees burning on the horizon (the Golgafrinchans had adopted the leaf as their currency and were fighting inflation by reducing the supply), feeling glad to be alive.

[[folder:Video Games]]
* The ending of ''LightningReturnsFinalFantasyXIII'' implies this; while the souls of humanity are travelling to the New World, we catch glimpses of what seems to be our solar system, along with a few distinctive geographical features of Earth. Lightning steps off a modern train into what looks like the French countryside, with French signs and 21st century cars. WordOfGod has stated that this is up to player interpretation, as it does create a few problems (such as the New World having no history).
* ''VideoGame/OdinSphere'' features the chipper, happy ending of [[spoiler:almost every human being on Earth dying horribly. However, two people survive, who presumably go on to become that world's [[AdamAndEvePlot equivalent of Adam and Eve]]. The game proper ends, followed by the FramingDevice (a little girl reading a storybook) complaining that it ended like that before noticing a coin on the cover very similar to one of the {{MacGuffin}}s in the book. As she walks away, a character from the stories appears and takes the coin, implying that the de facto Adam and Eve actually are.]]


[[AC:Before The Beginning or AfterTheEnd]]

[[folder:Anime and Manga]]
* An interesting manga variant with an {{Anvilicious}} [[AnAesop Aesop]], delivered by mangaka Creator/RumikoTakahashi in the early 1970's. A time vortex opens up in a classroom and starving primitive peasants spill out. Clues lead the class to assume that these are time-travelers from a historical famine centuries in the past. Since the class had been discussing the world's declining resources, they give huge amounts of food to the starving peasants before sending them home. "Home" turns out to be ''thirty years in the future'' - evidently the people in the past would end up sending so much food through the time portal to help "the past" that they would end up collapsing civilization.
* ''LightNovel/ScrappedPrincess'' does this to the viewer, with a small hint that something might not be as it seems being at the beginning of the very first episode, and nothing more said about it until partway through the series. Everyone in the show is seen to be living in a catchall generic Middle Ages fantasy setting, and to the viewer, it looks like just another ''{{LightNovel/Slayers}}''-esque[=/=]''Roleplay/RecordOfLodossWar''-type anime based in some nondescript magic world that is kind of like our world, but not. [[spoiler: However, the truth is that they're in the far future in "our" world, and their conquerors have regressed everyone back to the Middle Ages in order to prevent them from even wanting to mount a resistance. The "magic" seen in the series is actually MagicFromTechnology, based on the tech maintaining their "prison", which is actually a tiny piece of the world suspended in the sky.]] Then again, the very beginning of the show has a bit of AstronomicZoom that reveals the setting to be [[spoiler: Korea]].
* ''Manga/SorcererHunters'' does the same thing ''LightNovel/ScrappedPrincess'' did much less effectively (or more, considering that the above twist was an important part of the story in SP, but in SH, even if you suspected it somehow, it doesn't really matter until the end, and isn't even mentioned until the end). Long story short, in the final battle between Zaha and the Sorcerer Hunters, Zaha prepares a spell to unleash Carrot's power as the God of Destruction. Doing this requires them to be in the world that came before the world that the characters are now in, a world of death and destruction. The characters are transported to [[spoiler: what looks to be present day [[BigApplesauce New York City]], destroyed by some kind of apocalypse or war. Also, flashbacks of the characters are shown living their present day lives as the actions of the present and future converge.]] While this sounds kind of cool, trust me it's stupider than it sounds.
* ''Anime/TurnAGundam'' has a variation. The series takes place in a pre-industrial world, which makes it rather shocking when [[HumongousMecha mobile suits]] show up from the Moon. Partway into the series, it's hinted that some disaster (dubbed the Dark History) is the reason Earth is backwards while the Moon is advanced. The final act of the series is kicked off when we finally see what the Dark History was: all of the ''Franchise/{{Gundam}}'' universes made prior to ''Turn A'', including those not helmed by creator YoshiyukiTomino, [[WordOfGod who later said]] that the series was meant to put all of ''Gundam'' into a single timeline (hence the name, "Turn A", from the mathematical symbol meaning "all items in a set").

[[folder:Comic Books]]
* In the alternate-reality comic ''Comicbook/SupermanRedSon'', it is revealed that Superman [[spoiler:is the distant descendant of Lex Luthor sent [[TimeTravel back in time]]]], and Krypton [[spoiler:is actually Earth, destroyed by the death of the Sun.]]
* It turns out the [[OurFairiesAreDifferent Sheeda]] in ''Comicbook/SevenSoldiers'' aren't TheFairFolk, they're humans from the far future who go back in time to steal resources and technology.
* [[http://starwars.wikia.com/wiki/Into_the_Great_Unknown A non-canonical comic]] based on ''Franchise/StarWars'' has the ''Millennium Falcon'' crash on a distant planet; Han is killed by the natives. Years later, the ''Falcon''[='s=] wreck and Han's corpse are discovered by the famous archeologist... Franchise/IndianaJones. Who was trying to discover the Sasquatch, previously known as Chewbacca.

[[folder:Comic Strips]]
* ''ComicStrip/{{BC}}'' eventually implied that the strip was set AfterTheEnd complete with a cache of books from our time including Literature/TheBible.
* In ''ComicStrip/BrewsterRockitSpaceGuy,'' the titular character is on a visit to the planet Troglodonia, home of the Space Cavemen. One cave has a mural on its wall that depicts a visual history. It starts with a caveman, progresses through history (a gladiator, a car, etc.) before concluding with a mushroom cloud and another caveman.
-->'''Space-Caveman:''' Maybe planet older than we thought.

[[folder:Film -- Live-Action]]
* ''Film/FantasticPlanet''. The planet the Traags were inhabiting is left to the humans - and it becomes Earth.
* In the ''[[Series/MysteryScienceTheater3000 MST3K]]''-ified film ''Film/TeenageCaveman'', directed by the immortal Creator/RogerCorman, the TwistEnding is that it's AfterTheEnd, and not OneMillionBC. Although it may well be both; the one character who knows this suspects it isn't the first or last cycle, and his technology looks nothing like ours despite having similar function.
** The movie was based on ''By the Waters of Babylon'' -- see Literature, below.
* M. Night Shyamalan's ''Film/TheVillage'' [[spoiler:is actually set in the present day instead of the past. This is a variation in that it is the time period that the viewer is being deceived about, not the location]].
* ''Film/WomenOfThePrehistoricPlanet'', which you may remember from ''Series/MysteryScienceTheater3000'', features the accidental colonisation of Earth as a result from one of the few fictional vehicles ''ever'' to [[ShownTheirWork take relativity into account]].
* This is the main twist of ''Film/YorTheHunterFromTheFuture''. It starts out as a OneMillionBC movie with cavemen, a BarbarianHero fighting dinosaurs and strange creatures. It is only in the last third of the movie that they end up on an island run by a cybernetic EvilOverlord and his robotic minions that is revealed that this is really a posthistoric world after a nuclear holocaust. This is the film's excuse to include SpaceClothes, [[FamilyFriendlyFirearms laser guns]], and MechaMooks in the last act. Although the film's American title kind of gives it away; the original Italian version is titled ''Il mondo di Yor'' (The World of Yor), which makes the final act much more of a twist.

* In Creator/AlfredBester's short story ''Adam and No Eve'', an experimental space flight sets off a chain reaction that devastates and sterilized the world, leaving the pilot of the spaceship as the last survivor. [[spoiler: The story ends with the reveal that the planet will be reoccupied by life evolved from the pilot's gut microbes, and that present-day Earth is the result.]]
* The ''Ardneh Sequence'' by Fred Saberhagen, made up of the ''Literature/EmpireOfTheEast'' and ''Literature/BookOfSwords'' series, is fantasy set more than 50,000 years AfterTheEnd. Magic exists and the nuclear weapons that caused TheEnd have transformed into demons.
* The early Creator/PiersAnthony trilogy ''Battle Circle'' is set in a post-Apocalyptic world with various cultures ("nomads" and "crazies") living in the ruins.
* Stephen Vincent Benét's short story ''By the Waters of Babylon'' (1937) is this trope: the narrator, the son of a priest who is "immune" to a certain kind of metal that can kill everyone else in his tribe, narrates in such a way that you think he is a member of a primitive tribe that may or may not possess magic of some kind. By the end it is clear that [[spoiler:while there may be magic involved (specifically the flashback sequence), they most definitely are in the future, close to [[BigApplesauce New York]]. The holy metal spoken of is most likely radioactive, and the narrator, like his father, has inherited his radioactive immunity. The "Babylon" in the title is a ShoutOut to the town of that name on Long Island.]]
* The final book of ''Literature/TheDarkAngelTrilogy'' revealed that the setting, a fantastical alien world with month-long days, was Luna, terraformed ages ago. Earth's was incinerated in a global nuclear holocaust, and Luna had a civilization collapse to medieval fantasy levels.
* ''Literature/TheDeathGateCycle'' reveals towards the end of the series that it takes place after both a nuclear apocalypse and a magical one (which resulted in TheEndOfTheWorldAsWeKnowIt, hence the vastly different setting from our current planet).
* ''Literature/TheLaundrySeries'': A variant occurs in ''The Atrocity Archive'', in which a portal to another universe leads to a frozen, atmosphere-less planet with a sky of red stars. While the protagonists naturally assume this is some alien world, it turns out it's what's left of an alternate Earth in which the Nazis summoned an EldritchAbomination. It's nearly done eating that universe, and it's looking for a fresh buffet...
* The world of ''The Runestaff'', by Creator/MichaelMoorcock, is Earth in a distant future, where all technology is lost.
* The ''Literature/{{Shannara}}'' series is seemingly a medieval Fantasy setting with the usual FiveRaces, but it's revealed pretty early on to be an AfterTheEnd future.
* A ''Time Team'' story from ''3-2-1 Contact'' appears to be set in the distant past, but at the end [[spoiler: bulldozers show up]] the Time Team realizes that they are actually [[spoiler: in the present, in the middle of the Brazilian rain forest]].
* It's subtly hinted several times that the setting of ''Literature/TheWheelOfTime'' is our planet [[AfterTheEnd after not one but two world-changing catastrophes]].

[[folder:Live-Action TV]]
* In the 2000s ''Series/{{Battlestar Galactica|2003}}''... Well, it's complicated, but manages to touch pretty much all the versions of this trope:
** The ending of the first episode, when they revealed that the lost 13th colony that they were going to search for was called "Earth."
** AfterTheEnd: [[spoiler:When they finally reach Earth, it's a desolate wasteland, devastated thousands of years earlier by a war between human-form Cylons and the Centurions they'd built]]
** It Was Our Homeworld All Along: [[spoiler: The "final five" Cylons turn out to be the last survivors of Earth, which makes the long-sought thirteenth colony ''their'' homeworld]]
** It (Wasn't) Earth All Along: [[spoiler: The thirteenth colony was called Earth, but wasn't ''our'' home planet: our Earth is named after the earlier planet]]
** Before The Beginning: [[spoiler: The human and Cylon survivors decide to go native on a primitive but hospitable planet, which they decide to name "Earth" because after four years looking for a planet called Earth, they'll be damned if they're gonna settle. When we revisit the fate of this Earth 150,000 years later, we see New York City and [[CreatorCameo a man]] reading ''National Geographic'' -- as it turns out, the story is before our modern age, and we are all human-Cylon hybrids. BSG gets those double points mentioned at the top of the page, because of the Adama family name.]]
* ''Series/LandOfTheLost'': Not Earth, but a similar situation; an advanced, civilized Sleestak arrives in the Land of the Lost by TimeTravel, only to discover that the primitive Sleestaks aren't from his past, they're from his ''future'', AfterTheEnd.
* The planet Omega-IV in the ''Series/StarTrekTheOriginalSeries'' episode "The Omega Glory" is a bizarre case. The "[[EagleLand Yang]]" and the "[[DirtyCommunist Kohm]]" tribes are all that's left of their civilization after a UsefulNotes/ColdWar turned nuclear, and the resemblance to Earth comes to a head when the tattered, ancient American flag and U.S. Constitution put in appearances that leave the heroes stunned. But it's all the setup for a massive [[TheUnreveal unreveal]]. While a deleted scene would have suggested that the inhabitants are the human descendants of a LostColony, the mysteries are never resolved onscreen and Omega-IV is apparently just an alien planet that coincidentally reinvented America, the Soviet Union, China and the Cold War. (There were at least two other worlds in Original Trek that had cultures identical to Earth --five, if you count the Space Nazis who were explicitly given that information by an Earthman, the Space Gangsters who got it from an Earth book, and the Space Indians whose ancestors were actually from Earth.)

[[folder:Video Games]]
* ''VideoGame/EtrianOdyssey'' has a fairly typical medieval fantasy swords-and-sorcery setting, with some cryptic intro on the title screen about some disaster long ago that ended the previous age. This is shattered when you reach the fifth stratum in the first game, Lost Shinjuku (as in, [[http://en.wikipedia.org/wiki/Shinjuku this Shinjuku]], with the backgrounds looking almost exactly like those pictures and everything.) It turns out that [[ScienceIsBad recklessly advancing science and technology]] brought about global warming and miscellaneous environmental calamities to the point that Earth was an uninhabitable wasteland, killing off almost everyone. The few survivors started something called the [[MeaningfulName Yggdrasil Project]] to try to restore the environment, eventually leading to the low-population, completely lush greenery-everywhere medieval fantasy-looking world you're used to.
* The Konami arcade game ''Gaiapolis'' starts out looking like an alternate reality but reveals itself pretty late in the game to be an AfterTheEnd. TheReveal location? A massive graveyard watched over by mysterious robots.
* Quintet's ''Heaven And Earth'' series, which involves ''VideoGame/SoulBlazer'', ''VideoGame/IllusionOfGaia'', and ''VideoGame/{{Terranigma}}''. Although the first of those games doesn't explicitly claim to occur on Earth, it's a direct prequel to ''Illusion of Gaia'', which does (the ending reveals that Will's world eventually gave rise to modern civilization.) ''Terranigma'' is set long AfterTheEnd, but the player isn't clued into this until after the end of the first act.
** Of course, this all depends on you interpretation of the series. [[EpilepticTrees Fan theories]] give rise to every possible scenario from alternate dimensions, TimeTravel, to some sort of bizarre "NewGamePlus"-inspired theory that claims that the efforts of all three games lead to "our Earth".
* After defeating the God King in ''VideoGame/InfinityBlade'' and sitting through the credits, the Warrior accidentally triggers a holographic map of the world and its literally shattered moon. At first, the landmasses aren't instantly recognizable, but after a while Australia, Eurasia, and Africa rotate into view.
* ''VideoGame/LunarSilverStarStory'' seems to keep this aspect in the background and players barely notice it as the issue never comes up in the story proper. The planet Lunar is actually the moon of the Blue Star, the celestial object that is seen in the sky. According to legend, the Blue Star is where the Goddess Althena transplanted Lunar's residents from. It is mentioned that Lunar had to be terraformed by Althena. It doesn't take much to notice that the Blue Star is not a star but a blue planet. The most visible continents on the planet resemble Africa and Europe. Alex and the adventurers do visit the Frontier which appears as Lunar did pre-terraforming, which looks like the surface of the Moon.
* Indie-game ''VideoGame/OracleOfTao'' has this lampshaded from the ''very beginning'' of the game, along with a second world due to WorldSundering. The PlayableEpilogue omits the extra section, since the gate to this other world was presumably sealed.
* At the end of ''Scrapland'' the titular Scrapland is revealed to be the Earth during the BigBad's AsYouKnow speech.
* Most of the plot in ''VideoGame/SigmaStarSaga'' revolves around searching for a series of six planets which will ultimately lead to a DoomsdayDevice. [[spoiler: Earth is the "seventh" planet, which had already been destroyed by said device.]]
* ''VideoGame/{{Solatorobo}}'' is set in a Steampunk universe featuring PettingZooPeople who live on [[WorldInTheSky floating islands in the sky]]. Half way through the game however Human looking characters from the ancient world begin to show up. Eventually after traveling to (what's left of) the surface it's revealed that the game is set on far future Earth after Humanity went extinct in WorldWarIII. The Petting Zoo People and Floating Islands are the result of sentient supercomputers trying to reset life on the planet.
* Creator/{{Square|Enix}}soft loved to hint at this trope during their later SNES to early [=PlayStation=] years. ''VideoGame/SecretOfMana'' has a scene late in the game when the heroes find recordings of their world from its AndManGrewProud days, before the Mana Beast destroyed civilization and brought about [[TheMagicComesBack the return of magic]]. The recordings include country music, an episode of Jeopardy, news channel debates on the dangers of [[MagicFromTechnology mana energy]], and then a final broadcast of the Mana Beast attacking a city and then turning on the news crew that's filming the destruction. The implication is that the world of ''Secret of Mana'' is really Earth's distant future.
** Then in ''VideoGame/FinalFantasyVII'', we have an archeological dig that's uncovered what appears the ancient remains of a recognizable, real-world fighter jet. Fans debated the implications of that scene for years, though after the release of ''VideoGame/FinalFantasyX2'', WordOfGod has half-jokingly said that, rather than our world, the game actually takes place in [[VideoGame/FinalFantasyX Spira's]] far future.
** And in ''VideoGame/{{Xenogears}}'', the heroes find an underground city near the end of the game that looks like a modern metropolis and, within it, they find ancient newspapers making references to everything from Elvis Presley to the Wimbledon Cup (not to mention that the origins of the AncientConspiracy fueling the game's story bears a FauxSymbolism resemblance to the book of Genesis). WordOfGod later stepped in again to say that it's not Earth, but another planet far in Earth's future (though Earth does play an important, if unseen, role in that planet's backstory).
*** Not only that, but the game gives a more subtle hint that it might be our world: The chronology. The game takes place ten thousand years after the first humans began populating the planet. If one assumes Zeboim is modern or near-future Earth (given the technology it is clearly supposed to resemble it), and Zeboim died out 4000 years before the events of the game, then the game would take place circa 6,000 A.D., and the world's genesis story would have taken place circa 4,000 B.C, which is pretty much (23 Oct, 4,004 B.C.) when Bishop James Ussher calculated to be the date God got rolling on creating the world. WordOfGod may say it's not our world and of course that makes it true, but there are so many coincidences!
*** Using the Perfect Works chronology, Xenogears actually takes place in A.D. 17276-17277.
* ''VideoGame/{{Utawarerumono}}'' is set at a time where [[spoiler:the descendants of genetic experiments made during an apocalyptic period have repopulated Earth]]. This is a variation where you are led to believe that it is an alternate fantasy world. A pretty big clue comes when you see a strategic map view of the area and [[spoiler:the area around it is identical to the west coast of Japan, as seen from the east.]]

[[folder:Western Animation]]
* Subtly hinted at in ''WesternAnimation/AdventureTime''. The Land of Ooo appears to be a crazy fantasy world, but the opening credits and occasional references (along with WordOfGod) implies that it's actually AfterTheEnd. How all that magic suddenly started working is still anyone's guess.
** Confirmed in the Season 5 Premiere. A nuclear war caused mutagenic particles to spread, mutating all of the objects on Earth, and nearly driving humans to extinction. We also get to see an alternate timeline when the Mushroom Bomb was never detonated, and it appears to be mostly normal.
* Parodied in the ''WesternAnimation/{{Futurama}}'' episode "The Cryonic Woman", where Fry thinks that he is in New [[BigApplesauce New York]] AfterTheEnd, but it turns out to be current-time Los Angeles. Fry protests: "But there was this gang of 10-year olds with guns! But everyone is driving around in cars shooting at each other! But the air's green and there's no sign of civilisation whatsoever!" and his friends reply: "That's L. A. for you!"
** It then descends into satirical social commentary, where Fry cites, as proof that he's in a post-apocalyptic wasteland, the facts that nobody reads, everyone's a phony, and all the food has cilantro in it.
