A Great Flood is a mythic or traditional narrative in which overwhelming waters destroy, cleanse, or remake the human world. One person, family, or small group often survives and becomes part of a new beginning.

What is a Great Flood myth?
Great Flood stories place water between one world and the next. The flood may punish wrongdoing, end an exhausted age, erase a failed creation, or arise without a moral explanation. Survivors may escape in a boat, reach high ground, receive a warning, preserve animals or seeds, or rebuild society after the waters recede.
Not every flood tradition includes all of these elements. “Great Flood” is a comparative label for a family of narratives, not the title of one universal story.
Why flood stories are compared
Flood narratives appear in many regions, making them an important subject in comparative mythology. Some stories have a demonstrable literary relationship. Ancient Mesopotamian flood traditions, for example, survive in texts associated with Atrahasis and Gilgamesh and are frequently studied alongside the flood narrative in Genesis.
Other similarities may arise from recurring experiences of rivers, storms, tsunamis, changing coastlines, or the narrative power of water as both destruction and renewal. Similarity alone does not prove that every flood story descends from the same historical event or original tale.
Myth is not a geological report
A flood myth can preserve cultural memory, explain the present world, express religious ideas, or organize remembered disaster into story. Those possibilities should be investigated case by case. Folklore evidence by itself cannot establish that one worldwide flood occurred exactly as a particular narrative describes it.
Recurring motifs
- a warning given to a chosen survivor;
- a vessel, mountain, tree, or other place of refuge;
- the preservation of people, animals, food, seeds, or sacred knowledge;
- birds or other signs sent to test whether land has returned;
- a sacrifice, covenant, or new social order after survival;
- the beginning of a renewed human age.
