Cayce mentioned ancient America in 68 different readings. These readings covered migrations to America, mound builders, the Norse, and other events. In Mound Builders: Edgar Cayce’s Forgotten History of Ancient America (2001), his 68 readings on ancient America were extensively analyzed. From these readings, 30 specific statements were found which could be verified by scientific evidence. Of the 30 statements by Cayce, 23 (or seventy-seven percent) of them have enough support to be considered accurate. Another six statements are, as yet, not supportable by evidence, but could be verified in the future. Only one statement appears to be wrong. Thus, of all of Cayce’s seemingly impossible statements about ancient America, only 3% are definitely wrong. Of the remainder, 77% have been supported by scientific research, and the 20% that remain could be verified in the future.
