Crashing Eden by Michael Sussman
"Eden is a Sumerian word meaning lush plain. Some scholars believe that Eden was located in the Fertile Crescent. along the Tigris and Euphrates rivers, corresponding to modern-day Iraq. Around 6000 to 5000 BC, after thousands of years of drought, came a period called the Neolithic Wet Phase, when rains returned the the Gulf Region. Foraging populations also returned, but they found the area resettled by the first agriculturists. The Garden of Eden story may represent the point of view of the hunter-gatherers, who regarded the farmers as sinning against God by taking matters into their own hands, relying on their own knowledge and skills rather than on God's bounty."
