In the Persian Gulf are dozens of submerged sites of human habitations, stone foundations of buildings, because the Persian Gulf is only about a hundred feet deep so it was dry land during the Ice Age, as was the land now at the bottom of the Gulf of Suez (to the west of the Sinai peninsula) which is only about a hundred-fifty feet deep on average. No submerged ruins have been reported there perhaps for lack of looking, but considering the ruins in the Persian Gulf and dozens of other sites of submerged ruins in coastal water in many parts of the world, the Gulf of Suez is certainly a prime prospect for more.
