, often in an act of
divine retribution. Parallels are often drawn between the flood waters of these
myths and the primeval
cosmic ocean which appear in certain
creation myths, as the flood waters are described as a measure for the
cleansing of humanity, for example in preparation for
rebirth. Most flood myths also contain a
culture hero, who "represents the human craving for life".
The oldest known narrative of a
divinely inititated flood originates from the
Sumerian culture in

Mythologies
The ''
Epic of Gilgamesh'' (c. 2100–1800 BCE) references an early flood myth. This story has some parallels to the 18th century BCE epic ''
Atra-Hasis'', in which a group of Sumerian gods begins to transform Mesopotamia into a fertile garden landscape. The hard labour leads to a revolt of the ‘lower’ gods, and to pacify it, a first pair of humans was created to do the work in place of the gods. After a few thousand years, however, the humans have multiplied to such an extent that they disturb the gods with their noise, so
Enlil, the highest of all gods, decides to unleash a mighty flood to wipe out humanity. The rebellious god
Enki secretly warns his priest Athrahasis of the impending catastrophe. Giving him detailed instructions for building a boat, Athrahasis and his family survive, ensuring continued existence of artificially constructed mankind. In the
Gilgamesh flood myth, the flood is survived by the man
Utnapishtim. The similar
Eridu Genesis flood myth (), known from tablets found in the ruins of
Nippur in the late 1890s, was translated by assyriologist
Arno Poebel.
Academic Yi Samuel Chen analyzed various texts from the
Early Dynastic III Period through to the Old Babylonian Period, and argues that the flood narrative was only added in texts written during the
Old Babylonian Period. With regard to the
Sumerian King List, observations by experts have always indicated that the portion of the Sumerian King List talking about before the flood differs stylistically from the King List Proper. Old Babylonian copies tend to represent a tradition of before the flood apart from the actual King List, whereas the
Ur III copy of the King List and the duplicate from the Brockmon collection indicate that the King List Proper once existed independent of mention of the flood and the tradition of before the flood. Chen gives evidence to prove that the section of before the flood and references to the flood in the Sumerian King List were all later additions added in during the Old Babylonian Period, as the Sumerian King List went through updates and edits. The flood as a watershed in early history of the world was probably a new historiographical concept emerging in the Mesopotamian literary traditions during the Old Babylonian Period, as evident by the fact that the flood motif did not show up in the Ur III copy and that earliest chronographical sources related to the flood show up in the Old Babylonian Period. Chen also concludes that the name of "

, who had created man out of the dust of the ground,
decides to flood the earth because of the corrupted state of mankind. Yahweh then gives the protagonist,
Noah, instructions to build
an ark in order to preserve human and animal life. When the ark is completed, Noah, his family, and representatives of all the animals of the earth are called upon to enter the ark. When the destructive flood begins, all life outside of the ark perishes. After the waters recede, all those aboard the ark disembark and have Yahweh's promise that he will never judge the earth with a flood again. Yahweh causes a
rainbow to form as the sign of this promise.

Zoroastrian Mazdaism,
Ahriman tries to destroy the world with a drought, which
Mithra ends by shooting an arrow into a rock, from which a flood springs; one man survives in an ark with his cattle. Norbert Oettinger argues that the story of
Yima and the ''Vara'' was originally a flood myth, and the harsh winter was added in due to the dry nature of Eastern Iran, as flood myths did not have as much of an effect as harsh winters. He has argued that the mention of melted water flowing in
Videvdad 2.24 is a remnant of the flood myth, and mentions that the Indian flood myths originally had their protagonist as Yama, but it was changed to Manu later.

The
Cheyenne, a North American
Great Plains tribe, has a tradition where a flood altered the course of their history, perhaps occurring in the
Missouri River Valley. The
Blackfeet, another Great Plains tribe, have a story called "
Language on a Mountain". In this story the deity Napi, referred to as Old Man, tells the story of a great flood that swept through the land. After the flood Old Man made the water different colors. He gathered the people on top of a large mountain where he gave them water of different colors. Old Man then told the people to drink the water, then speak, and so they did.
Everyone was speaking a different language except those who received the black water; they were speaking the same language, and they consisted of the
bands of the Blackfoot, the
Piegan (Apatohsipikuni and Amskapipikuni), the
Siksika, and the
Blood (Kainai). This was said to have taken place in the highest mountain in the Montana
reservation.
The
Hopi, southwestern United States, have a tradition of a flood that nearly reached the tops of the mountains, and other
Puebloans have similar legends.
Historicity
Floods in the wake of the
Last Glacial Period (c. 115,000 – c. 11,700 years ago) are speculated to have inspired myths that survive to this day. Plato's allegory of
Atlantis is set over 9,000 years before his time, leading some scholars to suggest that a

Shuruppak ( , SU.KUR.RUki, "the healing place"), modern Tell Fara, was an ancient Sumerian city situated about 55 kilometres (35 mi) south of Nippur and 30 kilometers north of ancient Uruk on the banks of the Euphrates in Iraq's Al-Qādisiy ...

Jemdet Nasr and
Early Dynastic layers at the site were separated by a 60-cm yellow layer of alluvial sand and clay, indicating a flood, like that created by
river avulsion, a process common in the
Tigris–Euphrates river system. Similar layers have been recorded at other sites as well, all dating to different periods, which would be consistent with the nature of river avulsions.
Shuruppak in Mesopotamian legend was the city of
Uta-napishtim, the king who built a boat to survive the coming flood. The alluvial layer dates from around 2900 BC.

The geography of the Mesopotamian area changed considerably with the filling of the

Gulf Oasis for 100,000 years. A sudden increase in settlements above the present-day water level is recorded at around 7,500
BP.
Mediterranean Basin
The historian
Adrienne Mayor theorizes that global flood stories may have been inspired by ancient observations of seashells and fish fossils in inland and mountain areas. The ancient Greeks, Egyptians, and Romans all documented the discovery of such remains in such locations; the Greeks hypothesized that Earth had been covered by water on several occasions, citing the seashells and fish fossils found on mountain tops as evidence of this idea.

Black Sea deluge hypothesis
The
Black Sea deluge hypothesis offers a controversial account of long-term flooding; the hypothesis argues for a catastrophic irruption of water about 5600 BCE from the Mediterranean Sea into the
Black Sea basin. This has become the subject of considerable discussion. The
Younger Dryas impact hypothesis

Comets

The earliest known hypothesis about a comet that had a widespread effect on human populations can be attributed to
Edmond Halley

a worldwide flood had been the result of a near-miss by a comet. The issue was taken up in more detail by

, who argued in his book ''
A New Theory of the Earth'' (1696) that a comet encounter was the probable cause of the Biblical Flood of
Noah in 2342 BCE. Whiston also attributed the origins of the atmosphere and other significant changes in the Earth to the effects of comets.
In
Pierre-Simon Laplace's book ''Exposition Du Systême Du Monde'' (''The System of the World''), first published in 1796, he stated:
A similar hypothesis was popularized by Minnesota congressman and
pseudoarchaeology writer
Ignatius L. Donnelly in his book ''
Ragnarok: The Age of Fire and Gravel'' (1883), which followed his better-known book ''
Atlantis: The Antediluvian World'' (1882). In ''Ragnarok'', Donnelly argued that an enormous comet struck the Earth around 6,000 BCE to 9,000 BCE, destroying an advanced civilization on the "lost continent" of
Atlantis. Donnelly, following others before him, attributed the Biblical Flood to this event, which he hypothesized had also resulted in catastrophic fires and

. Shortly after the publication of ''Ragnarok'', one commenter noted, "Whiston ascertained that the deluge of Noah came from a comet's tail; but Donnelly has outdone Whiston, for he has shown that our planet has suffered not only from a cometary flood, but from cometary fire, and a cometary rain of stones."
