I don't know a lot about the Sumerians, other than the Jews seem to have lifted some of their stories from them. I read a couple of books by Zecharia Sitchen where he claims that his translations show a creation story by aliens for the purpose of our being their workers. While I can't verify his translations and have to take his word for it, I can say it makes much more sense than the all knowing God who gets no blame for anything but credit for all things (paradox anyone).
I did find his exploration into their vast astrological knowledge to be convincing, as they possessed knowledge out supposedly superior western science didn't until recent centuries. He said they claimed to be given that knowledge from out creators from outer space.
The Sumerians were a multitheistic society that predated all forms of organized monotheistic society. Many gods were the narrative before 1 god, this cultures existence alone exposes the fraud of Babylon. Supporters with a bias for Babylon will claim a lot of the lies they told were misconceptions of roman technology that was confused as roman, not Sumerian. We know now, that in Sumerian the predisposition for Babylon was well-known and they communicated those concerns through their vast network to the throne's in Babylon.
The high ups in Babylon knew very well of the technologies the sumerians were using and also feared them, so they destroyed them like the church has done with many other cultures;
Brian Muraresku has a good rebuttal for any ignorant theologian who claims divinity to the snake oil tale of the great flood. The Christian and Jewish myths of creation and superior being, were first interpreted while on shrooms in Eleusis, Greece. The visions of the goddess first experienced on drugs. This narrative will destroy what's left of those disorganized faiths.
It also exposed the fraud of 100% of the non-intoxicated Christians who after Abraham and Jude claimed to have a vision of the goddess without the psychedelic component.
