Even though I am very skeptical of the thesis that there was once an ancient advanced civilization on Earth (prior to those in the Middle East that arose circa 4,000BC following the invention of agriculture) that was lost to history, I nevertheless found this series fascinating. At least, the author does not couple his theory with the idea that the progenitors of this advanced civilization came from outer space, a hypothesis that without corroborating evidence is even harder to accept.
Instead, his basic idea seems to be that during the ice age, at a time when sea levels were much lower than they arew today, at least one civilization had become established on the planet. However, around 10,000 BC as the Ice Age ended sea levels rose precipitously destroying most physical evidence of said civilization in a series of cataclysmic events. Survivors of this civilization then roamed the earth seeking to transmit its teachings to bands of humans scattered about the planet.
