In 1947, Thor Heyerdahl set out to prove that Native South Americans could have peopled the islands of the South Pacific, transported on rafts made of lashed-together balsa logs, and catching fish with crude bone hooks and cruder nets. So he set out across the Pacific on a raft made of lashed-together balsa logs, catching fish with crude bone hooks and cruder nets. The book he wrote was Kon-Tiki.
Now that it is possible to use the technology of 23AndMe to trace lineages, it has been discovered that the indigenous people of the Amazon are closely related to the natives of Australia and New Guinea. Could it be that these people made the Kon-Tiki voyage in reverse as long as 50,000 years ago?
Archaeological anthropology is in an upheaval. The traditional view that humanity has been on a steady upswing for tens of thousands of years is challenged by (among others) Graham Hancock. He argues for the existence of a highly-developed ancient civilization based on mystical technologies rather than material ones. Noah’s flood was real. It came at the end of the last ice age, when a meteor struck the glacier that covered the entire American midwest and melted it in a flash. There followed the Great Forgetting, so we have only myths and verbal traditions to help us remember a time before 12,000 years ago.
