Genesis flood narrative
The Genesis flood narrative (chapters 6–9 of the Book of Genesis) is the Hebrew version of the universal flood myth. It tells of God's decision to return the universe to its pre-creation state of watery chaos and remake it through the microcosm of Noah's ark.
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 although many of its details are contradictory, the story forms a unified whole.
A global flood as described in this myth is inconsistent with the physical findings of geology, paleontology, and the global distribution of species. A branch of creationism known as flood geology is a pseudoscientific attempt to argue that such a global flood actually occurred. Some Christians have preferred to interpret the narrative as describing a local flood, instead of a global event.
