A common theme observed in legends of great floods is the motif of renewal and divine judgment. Many cultures recount stories, such as the Biblical tale of Noah or the Mesopotamian epic of Gilgamesh, where floods cleanse a corrupt world, allowing for a fresh start. These narratives often highlight the intervention of deities who decide the fate of humanity, signaling a strong moral undertone. Additionally, such myths frequently reflect natural disasters experienced throughout history, serving as metaphors for survival and the struggles of societies against overwhelming challenges. This theme emphasizes the cyclical nature of existence.
