Graham Hancock proposes the theory that a cataclysmic event occurred at the end of the last ice age, the Younger Dryas, which may be linked to many of ancient civilization’s flood myths, potentially pushing back many of today’s ancient megalithic structures thousands of years back from today’s archaeological dates.
Hancock gets criticized for challenging some of today’s archaeological paradigms, by proposing new theories with very interesting data and arguments. Bravo, Graham.
