I wouldn't exactly call this proof but you are on the right track. I did similar research years ago when I was still a Borg and was amazed to discover those ancient Mesopotamians wrote the "bible" long before the "bible" was ever dreamed up! Ever hear of the "Code of Hammurabi?"
Does this sound similar to something you have been reading as "god's word?"
