I think the garden of eden is a little farther down stream, but now underwater in the persian gulf. I actually got to go fishing in the gulf out from Kuwait city... few Miles out and it was only 20’ deep if that. I went to the city of Ur also... There had to have been wetter times for that place to have thrived. And when it dried out... The city died.
I have mixed feelings about what we understand about things that far back. But the bible gives lots of clues about some of it.
