Atlantis was a Maritime Civilization all over the world

A YouTube video entitled The Lost Continent of Atlantis includes an interview with Graham Hancock of Fingerprints of the Gods fame. In the video, Hancock says that he believe Atlantis was a Maritime civilization that settled along many of the coastlines of the world. At the end of the Ice Age around 12,500 B.C., when the ice melted, these coastal settlements became submerged. In Hancock’s opinion, therefore, Atlantean ruins will be found underwater all over the world. He sites both Mediterrean and eastern Atlantic Ocean ruins as examples of likely Atlantean sites.
