Ruins of ancient house foundations discovered on the seafloor of the Persian Gulf helped push along an odd hypothesis that the Garden of Eden is there submerged, that the four rivers of the Garden of Eden known biblically as the Tigris, Euphrates, Pishon, and Gihon are the Karun River (from the southern Zagros mountains) deemed the Pishon, and the Wadi Rummah (which begins near Medina in Arabia) into the Wadi al Batin called the Gihon (or vice versa), yet the confluence area of those all anciently flowing rivers is upstream from the Persian Gulf, and the four rivers of the Garden of Eden flowed out from a single magnificent gushing fountainhead at the center of the Garden now under thousands of feet of rock layers since Noah’s Flood (see Page titled Natural Selection by Noah’s Flood).
