During the Ice Age (which ended circa 1500 b. c.), the Persian Gulf was dry land (inhabited by Kushites, Elamites, and Joktanites) with the big Shatt al Arab river running through it down to the Arabian Sea, a beautiful flat land of shallow lakes and pastures where game abounded, no irrigation for agriculture needed, so that the Falaj irrigation system of the Arabs came into vogue circa 1300 b. c. is indicative that’s when the Ice Age had ended, when the very dry climate there became the norm.
