After Noah’s Flood circa 2350 b. c. when the repopulation of the earth was begun as Genesis 10 indicates, the isostatic adjustment of the earth’s crust dictated that the ancients build their ocean ports on rivers a bit upstream from their mouths, for instance Atlit Yam on the Oren river of ancient Canaan, and the city of Atlantis (built by Canaan’s son Sidon and his son Atlas) on the Guadalquiver river (Spain), which Plato said was five miles from the sea, submerged since circa 1500 b. c., the time of the Exodus.
