That would be pretty easily explained which I'm guessing you know. There is only one ocean. If the ocean suddenly broke through the strait between mainland Turkey and Europe and inundated thousands of square miles you can bet the same thing happened other places all over the world. I would imagine people living close to the original beach had boats on which some survived. I'm not believing the Alps, Himalayas, Rockies, etc. went under water. You don't believe that, do you?
Patriotism (and religion) is the last refuge of a scoundrel.
