Plato mentions in Timaeus and Critias a submerged country called Atlantis with a size about 540 x 190km, having a lake at one end with islands on it. It opens to a very large ocean with a narrow strait called Heracles Pillars. To the north of this fertile plain, through which a river flows and all kinds of plants and fruits grow, there is a high mountain range. Geological and archaeological data on the development of humanity indicate that the time before 12 thousand years coincided with an ice age. During the ice age, the sea receded from the Persian Gulf and there was only one lake with islands left near the Strait of Hormuz. The Persian Gulf turned into a continental area between 115 and 15 thousand years ago. The recovering of the Persian Gulf by the sea begins 14,000 years ago and ends 7,000 years ago. The modern humans emerged in East Africa 70,000 years ago, settled in this very fertile plain protected from the northern winds by the Zagros Mountains. When the plain began to be covered with the sea again people living there migrated to the Fertile Crescent region and formed the first social settlements. The Basra-Hormuz Plain is completely identical to the land of Atlantis described by Plato. Sumerian King List tablet contains sentences indicating clearly that Sumerian people migrated from an island to another during their past history. And all those islands must be at the bottom of Persian Gulf.
