The story takes place on present-day Earth. Maybe [[TwentyMinutesIntoTheFuture give or take a few decades]] or centuries. However, the world is really young. It doesn't have billions of years behind it, nope, it has only been around for a few thousand years.

Note that in theory, that doesn't have to mean that the world is created. However, a young Earth usually came with some kind of creator in the form of a God, alien, time-travelling human or simply an author writing the story of our lives. If the creator is a computer programmer and our world is just a simulation rather than the real Earth, then see instead InsideAComputerSystem.

In either case, what about [[UsefulNotes/{{Theorum}} all the scientific evidence that the world is much, much older]]? What about ancient fossils and radiometric dating? What about starlight that has traveled at light-speed from distant galaxies for billions of years, and so on? There are several approaches to this:

* ''The WillingSuspensionOfDisbelief approach'': The world is young, period. In ''this'' setting, science agrees [[MedievalStasis or is not practiced]], so no conflict.
* ''The ScienceIsWrong approach'': "Scientists believe the silliest things, lol. Evidence Schmevidence." A subtype of this is also found where the 'official' scientific explanations were created by an AncientConspiracy as a way of misleading the public about things which they'd prefer were kept secret.
* ''The [[StrawHypocrite It's-All-Political]] approach'': Similar to ScienceIsWrong. However, scientists aren't necessarily silly; but letting any evidence for a young earth speak for itself will end badly. Rather, they must conform their findings to forcibly fit a government-approved narrative if they wish to keep their grants (the Ben Stein documentary ''{{Film/Expelled}}'' is entirely dedicated to allegations this happens in RealLife to scientists who don't play by the rules). Public ignorance of a young earth in these settings isn't the work of an AncientConspiracy ''per se'', but is spurred on by the expediency of current government megalomaniacs, whose social engineering experiments would be seriously jeopardized if those old religious folk opposing them have an extra reason to feel justified doing so. A [[TheHeretic corrupt / apostate]] [[SinisterMinister theologian]] in league with the political PowersThatBe may be shown as using his status as TheMole to weaken the Church from within. A [[LaResistance resistance force]] of scientists who refuse to be intimidated by the government big machine is entirely optional.
* ''The JerkassGods approach'': Yeah, the evidence is there. But God or {{Satan}} placed it there as a MindScrew or a test.
* ''The {{Postmodern}} approach'': The world [[AllMythsAreTrue is as old or young as people believe it to be]], or simply a far stranger place than we can comprehend. The theory that the universe was created six minutes ago, assuming that we all spawned completely with memories and unwashed clothes and everything, is ''equally'' valid to any other theory: who said that time has to be linear, one-dimensional, or begin with creation anyway! The Earth might just as well have been created ''with a past'', or time has expanded backwards as well as forward.
* ''The LampshadeHanging approach'': God did put the ancient-looking dinosaur skeletons there and everything, but didn't mean anything by it. He was simply decorating His creation!

[[folder: Anime and Manga ]]

* In ''[[Anime/{{Urotsukidouji}} Legend of the Overfiend]]'', the world is only three thousand years old. The intro of the movie version also scolds Mankind for being so ignorant and foolish that they don't even know about parallel universes, so one can expect that people are supposed to simply shut up about their silly little theories about the origins of the universe.


[[folder: Comic Books ]]

* ''ComicBook/ChickTracts'' holds that Scientists are evil, and need to be cured of their heresy by the power of EasyEvangelism.
* In ''ComicBook/{{Preacher}}'', Literature/TheBible is literally true, and the reason we have reason to believe otherwise is that [[GodIsFlawed God is desperate to be loved]]: if our lives are HellOnEarth and we don't have any reason to believe that God even ''exists'' but we ''still'' love him anyway, then our love is such a sweet ego-boost in His eyes.
* ''ComicBook/TheSandman'' goes for the postmodern approach: time, history and reality are all very relative concepts, and what says that an act of creation can't be retroactive anyway? This is discussed in most albums, in one way or another.
** In ''A Dream of a Thousand Cats'' (a short story in the third book), the universe-as-we-know-it cannot possibly be older then a few years or decades - but the apocalypse wrote the old universe out of history, and created the new universe retroactively.
** The first albums of ''Comicbook/{{Lucifer}}'' averts this trope, however. In spite of Lucifer being a spin-off from Sandman. This version of the setting make it unambiguous that biblical events took place billions of years ago. Later albums kinda throw the concept of linear/objective time out of the window, returning us to square one.
* The ''Comicbook/{{Fables}}'' album ''The Great Fables Crossover'' takes the postmodernist approach: The world is the story we live in - it's recently written, and in danger of getting unwritten.
** By the power of CanonDiscontinuity, don't expect this to be true for the rest of TheVerse of Fables.
* Discussed in the ''Druuna / Morbus Gravis'' series. However, while it turns out to be true that Earth is young, it also turn out that [[spoiler: It's not really Earth! In the first album, the humans have forgotten that they are aboard a spaceship, and in later albums Druuna keep forgetting that she's trapped in a DreamWithinADream which is trapped in a telepathic HiveMind which is trapped inside a crazy computer. The third album starts with the words "In the beginning there was chaos. Then God created the supreme being... first among all creatures: Himself." This turns out to have happened quite recently, but one need to question the concept of "universe" anyway.]]


[[folder: Fan Works ]]

* One alternate continuity for ''TabletopGame/OldWorldOfDarkness'' takes place on present-day Earth in a universe where time itself started only 20,000 years ago but wasn't created. Instead, Earth evolved. Yes, Earth itself, not just life on earth. It was a mnemonic evolution rather then a biological one. In this setting, physical reality is a mirror of the human mind's conception of reality, not the other way around. The planet started out as small and flat, later grew round, and now a whole universe is popping up around it in accordance to mankind's ever-growing consciousness.
** The magic spheres of TabletopGame/MageTheAscension was always there, the 42 first humans were mages. Since linear time hadn't been invented yet, they were also each other's ancestors. [[TabletopGame/WerewolfTheApocalypse Shapeshifting]] was early, too. Much later, when heaven and hell came into existence, people wouldn't reincarnate anymore. So the Illuminati created TabletopGame/{{vampir|eTheMasquerade}}ism to stay in the world.
* ''[[ Omphalos]]'' by Marcus Rowland is a ''Series/BuffyTheVampireSlayer / Series/StarTrekDeepSpaceNine'' crossover that discusses the JerkassGods version. [[spoiler: While experimenting with the Key, Dawn accidentally creates the ''Series/StarTrekDeepSpaceNine'' universe. It comes into being at the beginning of the story, but all the characters remember their full histories, as if they have always existed.]]


[[folder: Film ]]

* In the movie version of ''Film/LeftBehind'', Literature/TheBible is literally true, period [[note]]Specifically, the idea of "literally true" that the authors' church teaches, which includes quite a bit of WordOfDante and is vastly different from mainstream Christian teachings[[/note]]. Critical thinking doesn't exist in this setting, and it works both ways. Protagonists who spent their entire lives with a secular world-view don't seem to feel ''any'' need for any explanation of how young earth creationism can possibly be true. In return, the rapture actually happening doesn't seem to give anyone else the idea that evangelical Christianity might be true after all.
** The fanfic [[ | "Left Beyond"]] leaves it ambiguous whether the Young Earth is true or the result of a liminality/pocket universe superimposing on the real one.


[[folder: Literature ]]

* In ''Literature/GoodOmens'', the Earth has only been around for 6,000 years and all the 'old' stuff in the ground is God's decoration.
** It also mentions that fossils are a joke that the paleontologists haven't seen yet (a BrickJoke in progress).
* In ''Literature/{{Strata}}'', the main character designs planets for a living, and it is explained that it is important to give each planet a "history" to make it feel like something billions of years old rather than just a big lump of rock. At the end of the book it turns out that the entire Universe was constructed with this in mind and is only a few thousand years old.
* In ''Literature/TheHitchhikersGuideToTheGalaxy1'', the Earth is only 10 million years old (this may not sound young, but it's equivalent to thinking someone is 70 years old and finding out that he's 8 weeks old. [[spoiler:It is also commissioned by mice, the true masters of our world.]]) Slartibartfast mentions that fake dinosaur fossils were installed during the planet's construction.
* ''Literature/JobAComedyOfJustice'' has the world created recently, as a joke. As Satan puts it at one point, "My brother Jehovah is a bit of a jerk." What bothers Satan about the world is mostly that Jehovah stole most of the design. [[spoiler:(It turns out that all this world-making, by a whole host of divine beings, under the review of another class of beings described as being "as far above me as I am above you" is all some cosmic artistic expression. As Satan explains, "This isn't about justice. This is about art.")]]
* The ShortStory ''Evolving Conspiracy'' by Roger [=McBride=] Allen gives a nice metaphor for the postmodern approach: in order to make it seem that someone has slept in a bed, what would be the best way to achieve this? ''Actually'' sleeping in said bed. And God, being the master over space ''and time'', did just that in 4004 BC.
* ''Literature/TheCosmere'': Most of the worlds are implied to be very young, with estimates putting them at somewhere between five thousand to ten thousand years. This, of course, is because after the original human homeworld was destroyed by the [[{{Deicide}} death of Adonalsium]], the god-like Shards spread throughout the Cosmere to terraform worlds of their own. Though how this worked is not examined in depth, there are some theories; [[Literature/TheStormlightArchive Roshar]] is heavily implied to have had life before Honor and Cultivation brought humans, while [[Franchise/{{Mistborn}} Scadrial]] was almost certainly just a dead rock before Ruin and Preservation arrived. WordOfGod is that Scadrial had no fossil fuels before the new god, Harmony, put them there during the Catecandre. He knew the people would need them if they were going to advance technology at a reasonable rate. That being said, since Harmony left behind a book detailing his experiences in reshaping the world, it's most likely that the people understand exactly how old their world is, dodging the UnfortunateImplications of a god implicitly lying by adding fossil fuels to a young world.


[[folder: Music ]]

* Played for laughs in Music/{{SPOCK}}'s song ''Alien Attack'': It starts out as a straight case of the "Science is wrong" approach, ranting about how geology is just a theory that shouldn't be trusted. After thus establishing the character as a creationist conspiracy theorist, the concept changes. It turns out that they are not talking about the earth being young (which would have made more sense from the first lines). Instead, they are talking about how the dinosaurs actually survived the extinction level event by fleeing out into space. Now they are back, and furious that the humans evolved and took over their planet in their absence.
** ''"Alien, alien attack. [[PunctuatedForEmphasis They. Want. Their. Planet. Back.]]"''


[[folder: Tabletop Games ]]

* The TabletopGame/OldWorldOfDarkness is young, [[NonIndicativeName ironically enough]].
* ''TabletopGame/{{Nobilis}}'' has a [[MindScrew characteristically odd]] version of the JerkassGods approach. The apparent age of Earth joins ''all other logical scientific principles'' in being the [[GeniusLoci world's own]] delusion, called Prosaic Reality. It [[ExtraStrengthMasquerade keeps mortals entrapped]] via continual CosmicRetcon.
** The ''reason'' for this strange situation also bears mentioning: A couple of thousand years ago, an [[LightIsNotGood Angel]] came to Earth. He was so offended when he saw a very large dinosaur defecate, he [[DisproportionateRetribution wiped them from the face of the planet]]. Prosaic is evidently the world-spirit's attempt to create a reality where such horrifying things at least happen for reasons more comprehensible than a god's whim.
** Despite the fact that they're delusions, these are ''not'' a bad thing. Yes, they're lies hiding the true wonder of the world from humanity... but the true wonder of the world is rather inimical to human life and sanity -- there's a special and dangerous kind of insanity that plagues non-miraculous beings that suddenly discover the Prosaic World is a lie through direct exposure to miracles. Few people can function with the knowledge that ''everything'' is alive, and at the incomprehensible whim of a god, they might not just be turned into a cat, but have suddenly never been anything ''except'' a cat.
* While not all ''that'' young, the Earth of the ''TabletopGame/{{Nephilim}}'' gameworld is only a few million years old. The various [[AncientConspiracy secret societies]] have manipulated 'science' to [[TheMasquerade disguise the real nature of reality]] from the lowly mortals.
** In the French edition, perhaps, but the English adaption used the Indian Yuga calendar, explaining Earth as being 4 billion years old. The difference is that it was formed by the reflection of sunlight off the other planets (and the Moon) all directing toward a single point, which formed the Earth's core and soon after the rest of the Earth. Animal life is the result of moonlight and direct sunlight struggling against one another.
* ''TabletopGame/{{Exalted}}'' uses a variant of this, with the back-cover explaining that ScienceIsWrong about pretty much everything in general and the age of the world in particular.


[[folder: Video Games ]]

* [[ChurchOfHappyology The Epsilon Program]] in ''VideoGame/GrandTheftAutoSanAndreas'' believes that the world is only ''157'' years old. And that it stays exactly that old.


[[folder: Miscellaneous ]]

* The ParodyReligion of Last Thursdayism claims that the Universe was actually created [[ExactlyWhatItSaysOnTheTin last Thursday]], and any memories or evidence of events before that were created at the same time.
** The schism known as Next Thursdayism claims that the universe ''hasn't been created yet'', and what we think is happening now is just false memories we'll have [[MindScrew once it exists]]. Of course, some might argue that both sides are heretics: The Universe was created Last ''Tuesday'', and is in fact created every Tuesday.
