Quote:Landsberger called the pre-Sumerian language simply Proto-Euphratian. Other scholars suggest that its speakers were the Ubaidians. However it was, the existing names were incorporated into Sumerian and written down for the first time. And the mythology of the lush and lovely spot called Eden was codified by being written.
“The whole Garden of Eden story, however, when finally written, could be seen to represent the point of view of the hunter gatherers,” Zarins reasons. “It was the result of tension between the two groups, the collision of two ways of life. Adam and Eve were heirs to natural bounty. They had everything they needed. But they sinned and were expelled. How did they sin? By challenging God's very omnipotence. In so doing they represented the agriculturists, the upstarts who insisted on taking matters into their own hands, relying upon their knowledge and their own skills rather than on His bounty.
