A flood myth or a deluge myth is a myth in which a great flood, usually sent by a deity or deities, destroys civilization, often in an act of divine retribution. Parallels are often drawn between the flood waters of these myths and the primeval waters which appear in certain creation myths, as the flood waters are described as a measure for the cleansing of humanity, in preparation for rebirth. Most flood myths also contain a culture hero, who "represents the human craving for life".[1]
The flood-myth motif occurs in many cultures, including the manvantara-sandhya in Hinduism, Deucalion and Pyrrha in Greek mythology, the Genesis flood narrative, the Mesopotamian flood stories, and the Cheyenne flood story.
