Genesis 8:3

"And the waters returned from off the earth continually: and after the end of a hundred and fifty days the waters decreased."

So vast a subsidence of such tremendous amounts of water could have been caused by a phenomenal reduction of the earth's elevation "that lowered sea beds"[5] which had previously been abnormally elevated by such a disturbance as an earthquake, or other geological changes. The strange legend (if it is legend) of the disappearance of the fabled city of Atlantis could well have been founded on events related to the Deluge. Plato accepted that tale as a fact, and well it could have been. If indeed there was buried beneath the waves of the Atlantic ocean, named after the lost continent, an ancient antediluvian civilization, the logical cause of it would have been these changes evident in the Genesis account of the Flood.
