Flood mythology refers to the various stories and legends found in different cultures that describe a great flood sent by deities to cleanse the world or punish humanity. These myths often feature a hero who survives the flood, typically by building a large boat or ark. Examples include the Epic of Gilgamesh from ancient Mesopotamia and the biblical account of Noah's Ark in the Book of Genesis. Many flood myths share common themes, such as the idea of rebirth and renewal following destruction. They often reflect the cultural values and environmental experiences of the societies that created them, highlighting humanity's relationship with nature and the divine.
