A common CreationMyth {{motif}}: the world, {{God}}, or some [[OurTitansAreDifferent primordial entity]] comes into existence by hatching from an egg or similar structure.

This is generally used so that the universe's life-cycle mimics those of many of its creatures, giving the trope metaphorical significance as a symbol of life's beginning. As such, it is found in many religious stories and ancient mythologies, but it is also commonly found in many modern {{Mythopoeia}}s as a way to begin the narrative. Sometimes the egg is laid by a goddess or creature that existed before the universe did, thus overlapping this trope with WhaleEgg.

See also PrimordialChaos, which may be where these are located, and WorldTree, which has similar connotations.

* According to one story, this is how ComicBook/{{Galactus}} managed to survive the last big crunch.
* This is how worlds are born in ''ComicBook/TheBooksOfMagic''. Tim restores the dying realm of Faerie by finding a world egg to hatch a new Faerie.
* ''ComicBook/BuffyTheVampireSlayer'' season 8 shows the Seed of Wonder, which has the shape of a red egg about the size of a football. According to Spike, "The world came from the Seed."

* This trope is played straight with the Cosmic Egg making an appearance in the third novel of the ''Literature/AstralDawn'' series (Design of Destiny). Caspian has to find the Cosmic Egg and retrieve the Sword of Fracture from it.
* In ''Literature/TheGodsThemselves'' by Creator/IsaacAsimov, these are used as ''[[PoweredByAForsakenChild fuel]]''.
* One of the [[MultipleChoicePast many origins]] of the ''Literature/{{Discworld}}'' universe given by the Great Spells in ''Discworld/TheLightFantastic''. Apparently, the Cosmic Egg was "distinctly rubbery."
** And in the Literature/{{Discworld}} novel Discworld/{{Eric}}, it turns out that early bacterial life was given a jump-start by Rincewind (who had gone back in time) tossing away the '''Egg'''-and-Cress sandwich given to him by The Creator.
** An egg of stone (a geode) is also central to the dwarfs' origin myth which explains how the dwarfs, the humans, and the trolls were created.
* Appears in ''Literature/TauZero'' at the end of the universe, during the Big Crunch.
* In ''Fossil Hunter,'' book two of The {{Literature/Quintaglio Ascension}}, the prologue is an excerpt from the first sacred scroll, the Quintaglio religious text: ''[-Five thousand kilodays ago, God laid the eight eggs of creation. When they hatched, the world was born.-]''

* Provided the name and album cover for Music/{{Wolfmother}}'s second full album.
* Music/{{Bjork}}'s song "Cosmogony": "And they say back then our universe was a cold black egg/Until the god inside burst out and from its shattered shell/He made what became the world we know."

[[AC:Religion and Mythology]]
* OlderThanDirt: The Rig Veda (and later, some Puranas) use this to describe the universe in its early stages in Myth/HinduMythology.
* The [[http://en.wikipedia.org/wiki/Orphic_Egg Orphic Egg]] of [[http://en.wikipedia.org/wiki/Pelasgian_creation_myth#Pelasgian_creation_myth Pelasgian creation myth]] which predates Myth/ClassicalMythology and even the Greek language.
* The Taoist idea of Pangu from Myth/ChineseMythology is this trope.
* Mentioned in the ''Literature/{{Kalevala}}''.
* [[Myth/EgyptianMythology Egyptian]] [[http://www.mythome.org/creategy.html myth has a creation story involving an egg.]]
* In Hawaiian mythology, the fire-goddess Pele carries [[EggMacGuffin an egg]] from her original home in Tahiti to the Hawaiian archipelago. The egg hatches out her fully-formed sister [[NaiveEverygirl Hi'iaka]], the goddess of dance. (In fact, Hi'iaka's much longer full name translates (very) roughly as "carried in the arms of Pele").

* ''Webcomic/{{Homestuck}}'': Skaia more or less fits this description.

[[AC: WebOriginal]]
* [[http://wanderers-library.wikidot.com/eggshells Eggshells]] from ''Wiki/TheWanderersLibrary''.

* This is said to be the theory behind Reality Marbles in the Franchise/{{Nasuverse}} -- the MentalWorld of the magus is what's inside the CosmicEgg, and the Reality Marble is the ability to switch the world outside the egg with the world inside. This "creation" is only temporary though; since the event is an unnatural occurrence, the larger world will attempt to revert the disturbance back to normal, which is why Reality Marbles require a large amount of prana to maintain even for a few minutes.
* Rosalina's starship, in ''SuperMarioGalaxy'' has a warp field that makes it look like an egg. Given that she's apparently the overseer of the rebirth of the universe, this is likely intentional.
* Arceus is a godlike Franchise/{{Pokemon}} who supposedly "hatched from an egg in a place where there was nothing" before [[CreationMyth creating the world.]] Also, he'll create you one with one of the [[VideoGame/PokemonDiamondAndPearl Sinnoh legendaries]] in a ''[[VideoGame/PokemonGoldAndSilver Heartgold and Soulsilver]]'' event.
* While it's never stated whether or not the universe itself hatched from them, the Cosmic Eggs of ''VideoGame/ShinMegamiTenseiStrangeJourney'' [[EndOfTheWorldSpecial have the power to remake the Earth as a world of absolute Law or Chaos.]] [[spoiler: [[TakeAThirdOption They can also be detonated in order to destroy the Schwarzwelt instead.]]]]
** [[MythologyGag By gum]], Tokyo in ''VideoGame/ShinMegamiTenseiIIINocturne'' sure is round like the inside of a cosmic egg! Which it is, and it's up to the main character to determine what kind of world will emerge from it. [[spoiler:Or he can destroy the restarter mechanism and goes on a RageAgainstTheHeavens.]]
** In ''VideoGame/ShinMegamiTenseiIVApocalypse'', Krishna's ultimate goal is to turn his [[TheDragon pet snake Shesha]] into the Cosmic Egg, from which a new Universe separate from [[{{God}} YHVH's]] jurisdiction would be created. It sounds fine and dandy (especially when you consider [[GodIsEvil what sort of god YHVH is in this setting]]), but unfortunately, Shesha needs to consume boatloads of human souls to gain enough power to become the Cosmic Egg, and this forces an alliance of all of the other warring factions in the game to stop Krishna and his allies from realizing their goal. Later, [[spoiler:Shesha succeeds in becoming the Cosmic Egg, though it's up to the player to decide whether they will use it to create a new Universe, or to destroy it]].
* In ''VideoGame/OracleOfTao'', Ambrosia uses one of these to make all existence real [[spoiler: (before that, it was more a LotusEaterMachine with herself as the only real person)]].
* The Precursor stone in ''VideoGame/JakIIRenegade'' is the last Precursor egg.
* Several religions in ''Franchise/TheElderScrolls'' have this motif.
* ''VideoGame/DragonBallXenoverse2'' uses one of these as a MacGuffin. Tokitoki, the pet bird of the [[TimeMaster Supreme Kai of Time]], has laid an egg that will eventually give rise to a brand-new universe; [[BigBad Towa]] wants it because the massive energy contained within could help her revive the Demon Realm. [[spoiler:[[DragonWithAnAgenda Mira]] ends up absorbing the egg -- '''and''' Towa -- achieving a level of power on par with [[Anime/DragonBallGT Super Saiyan 4]]. With Goku's help, the PlayerCharacter is able to recover the egg before defeating Mira.]]

[[AC:Real Life]]
* The very Big Bang itself. In fact [[https://en.wikipedia.org/wiki/Georges_Lemaitre Georges Lemaître]], the first scientist to suggest that origin for the Universe, originally referred to it as a cosmic egg.
