Flood narratives are stories found in various cultures that describe a great flood sent by a deity or natural forces to cleanse the world or punish humanity. These tales often feature a chosen individual or group who survives the flood, typically by building a vessel, such as an ark, to save themselves and a selection of animals. Many ancient civilizations, including the Mesopotamians, Greeks, and Indigenous peoples, have their own versions of flood myths. The most well-known example is the Biblical account of Noah's Ark, which shares similarities with other flood stories, highlighting common themes of destruction and renewal across cultures.
