Thx, Eric, will do...
I was both amused and gratified to learn that the Sumerian civilization[s], which date back several thousand years before the bible was written, were located between the Tigris and Euphrates rivers.... The Sumerians became experts [within their time] at agriculture and irrigation... Their river-bottom croplands must have looked like an abundant garden to any ignorant, nomadic Middle-Eastern herdsmen who might have come across their green fields and gardens...
What an interesting coincidence...
