I am sure the old Sumerian copied the Old Testament, but Jesus himself confirmed that the Jews were the ones with the correct text, so for me personally, I could not care less about old Sumerian texts.

My faith is in what the Bible tells me, not what a Pastor preaches. I am well aware that the harlot Church offer alms to forgive sins, there was a whole Reformation over this, among other things. Come out of her, that be my advice.
