The most recent cosmic catastrophe of consequence apparently occurred only about 13,000 years (11,000 BC) ago. It is said to have been associated with the Great Deluge, referred to within a large number of folk memories all over the world. A few people must have survived this Universal Deluge to talk about it, and thus have it incorporated eventually in their tribal memories.
Zachariah Sitchin, in ‘There were giants upon the Earth,’ dates the Deluge (Noah’s Deluge) at about 13,000 years ago. His work was based on his interpretation of the cuneiform writings of the Sumerians. (It would appear that the Old Testament drew, in part, upon these Sumerian records.) Sitchin’s previous books appear to have influenced D.S. Allan and J.B. Delair in their work ‘Cataclysm: compelling evidence of a cosmic catastrophe in 9500 BC.’
In his Foreward to the latter book, Rand Flem-Ath (co-author of ‘When the sky fell’) refers to the destruction of Atlantis as having occurred between 9559 BC and 9594 BC. He drew upon Plato’s writing about his ancestor, Solon; ‘a learned Egyptian priest’ reportedly told Solon about the legend of Atlantis.
The subsidence of the mythical Atlantis has been linked to the subsidence of Appalachia (or North Atlantis), Fennoscandia, Beringia, the ‘Southern Continent’ in the Indian Ocean, and a great Pacific continent.
Only a major collision caused by a very powerful or very large object from space could have caused this level of subsidence. There were apparently other major consequences. Dating the causal Event at about 11,000 to 13,000 years ago seems credible, since modern civilisation allegedly commenced only about 8,000 BC.
What is known about the cause of the Event?
