There is disturbing new scientific evidence that multiple fragments of a giant comet struck the earth in a series of cataclysmic bombardments between 12,800 and 11,600 years ago. The impacts brought the last Ice Age to an end and caused worldwide extinctions of animal species. Established theories about the emergence of civilization place the invention of agriculture and monumental architecture if the bombardment itself are nor taken into account by archaeologist seeking to explain the origins of civilization. What the record attest to, Graham Hancock demonstrates in Magicians of the Gods, is not the sudden "invention" of new and previously unknown skills, but a transfer of technology to hunter-gatherers from the survivors of a more advanced, lost civilization.
