"In the early chapters of Genesis, people live 800 years, 700 years, 900 years," said Rabbi Burt Visotzky, a professor of Talmud and Rabbinics at the Jewish Theological Seminary in New York. "Those are mythic numbers, those are way too big. We don't quite know what to do with that. So sometimes those large numbers, I think, also serve to reinforce the mystery of the text."Some of the details of the Noah story seem mythical, so many biblical scholars believe the story of Noah and the Ark was inspired by the legendary flood stories of nearby Mesopotamia, in particular "The Epic of Gilgamesh." These ancient narratives were already being passed down from one generation to the next, centuries before Noah appeared in the Bible."The earlier Mesopotamian stories are very similar where the gods are sending a flood to wipe out humans," said biblical archaeologist Eric Cline. "There's one man they choose to survive. He builds a boat and brings on animals and lands on a mountain and lives happily ever after? I would argue that it's the same story."
