The Genesis flood narrative (chapters 6–9 of the Book of Genesis) is a Hebrew flood myth. It tells of God's decision to destroy creation, saving only Noah and the people and animals who went with him into an ark built on God's instructions.
The Book of Genesis was probably composed around the 5th century BCE; although some scholars believe that primeval history (chapters 1–11), including the flood narrative, may have been composed and added as late as the 3rd century BCE. It draws on two sources, called the Priestly source and the non-Priestly or Yahwist, and many of its details are contradictory.
