Derek S. Allan & J. Bernard Delair are two British scientists who authored a book[014], which discusses a global catastrophe that affected the planet during the 10th millennium BC. They have built upon and refined the catastrophist theories of Velikovsky [037][038]. Drawing on the details of worldwide myths and recent scientific research they have developed a plausible argument for 
believing that the Earth was violently impacted upon by an extraterrestrial event over eleven thousand years ago. Their contention is that ejecta, of varying sizes, from a nearby supernova, entered our solar system resulting in devastation on a planetary scale. The Earth did not escape and the destruction visited on our world is the sobering subject of this book.
The authors boldly challenge accepted Ice Age theory, denying that the usual evidence of glacial damage is correct as such striations are found in areas that did not have to endure an ice age! This book will no doubt require revision, as our understanding of the past develops, but for the present it offers an insight into the incredible disasters that could have wiped out our ancestors. Delair wryly commented that evolution may not be just the survival of the fittest but also the survival of the luckiest.
Allan & Delair have used scientific evidence to indicate that 9500 BC was the approximate date for their proposed cataclysm. The coincidence of this date with the date related to Solon, has been seized upon by the more fundamentalist Atlantologists, who insist that Plato’s early date for the destruction of Atlantis is, euphemistically speaking, written in stone.
