A good video! I don't even think that a story like Noah's was made up, just blown up in the telling and retelling. He probably loaded his family, two goats and the dog in a rowingboat when his valley flooded - quite an event for a solitary family. Once you see that pattern, you see it everywhere: in Gilgamesh, the Mahabharata or the bible. Read with this idea, the stories are much more human and enjoyable.
