Cataclysm: Compelling Evidence of a Cosmic Catastrophe in 9,500 BC.
Cataclysm: Compelling Evidence of a Cosmic Catastrophe in 9,500 BC.  by D.S. Allan and J.B. Delair was originally published as When the Earth Nearly Died (Gateway Books,1995)(a). This book discusses in detail the nature of the catastrophe that engulfed our planet 11,500 years ago. This controversial book challenges many of the accepted ideas regarding the last Ice Age. The authors attribute the extinction of many species such as the mastodons and mammoths to this prehistoric catastrophe. Ancient traditions and mythologies are offered as evidence of this global cataclysm that included enormous floods, conflagrations and massive geological upheavals. Allan and Delair are convinced that these worldwide convulsions were caused by the intrusion into our solar system by a comet known to the Babylonians as Marduk and to the Greeks as Phaëton. They further contend that this comet had a dramatic effect on both our moon and Mars. However contentious this book may be, it is certainly a worthwhile read. For students of the Atlantis story, the coincidence of Plato’s date for the collapse of Atlantis with the date offered by Allan & Delair for the worldwide disasters is of great interest.
Paul A. LaViolette, who has written extensively on physics and astronomy, is the author of a similarly themed book. Dr LaViolette contends that over 10,000 years ago the Earth was subjected to intense radiation from a nearby nova that led to the extinction of over 90% of animal species.
