“Humans passing this story for hundreds of years and at some point in time an anonymous person putting it in writing and then other anonymous authors writing their own version of the story at different points in time.”
In almost every civilization there is a flood story with a boat and a family. Interesting that WSJ seems to say that “this story” may come from one actual event; whereas current culture says the Bible is wrong and that all flood stories are referring to some local event.
Genesis 11:1-9 explains how all cultures have a story of a flood, a boat and a family.
