Where was Babylon? In Mesopotamia - which included present day Iraq. Where was Abraham born, raised and from where he began his journey which led through what is now Arabia? Abraham was born in the Mesopotamian city of Ur, which was about 200 miles southeast of present day Baghdad.
Finding the earliest accounts of the “biblical flood” story in Mesopotamia is no surprise. In fact, given Abraham’s place of origin and that the stories of Genesis were passed on into Judaism by Abraham and his family and friends, it is quite normal for some of the oldest tales from the bible to be found near where the story of Abraham begins.
A lot of Jews were ‘moved’ to Babylon and became integrated into that society sharing history and education.
Hatred of the source of these writings aside... The timeline of the writings tells all in which came first and who plagiarized who. Funny thing is, all this hatred is misdirected, Islam wasn’t even born yet to hate. Sometimes the ignorance and hatred of extremists just astounds me. It is an absolute wonder we learn anything from real history at all.
