“You are assuming that some civilization came up with the narrative before Genesis was âinventedâ. Genesis was the written form of what was orally passed down for centuries before someone compiled it all into written form. That is why a lot of it is lost in translation and written from the perspective of a primitive mind (such as describing the night sky as a dome over the earth).”
Let’s use the logic that G-d gave our minds the ability to use and comprehend.
I think that the Garden of Eden story comes from Mesopotamia. So does the Gilgamesh story.
This is the place where Abraham came from so there’s the link to pass them on orally.
