Haven't read this yet, but I heard the author interviewed on CBC radio and I was intrigued. The book is available on the Amazon UK and Canada sites now. Basically, his thesis is that the 'accidental discovery' of powerful hallucinogens by humans, was the trigger that gave birth to our current system of beliefs in deities - that it happened all over the world at a sudden moment in human history, and can be documented by numerous cave drawings in many different places, all more or less depicting the same "religious" experience. We ate some plants that altered our references (not to mention our neurons) so drastically, that we were compelled from then on to construct susperstitions and dogmas, to somehow 'substantiate' the visions or myths. Drugs fucked us up and now we're fucked up on religion-- y'know what, it kind of makes sense to me.

I love Graham Hancock-yes he has an agenda and is not an unbiased researcher, but his stuff is fascinating. He spent all this time doing hallucinogens and shit and had all these experiences and wrote about it in the name of anthropology. His interpretation is not that we only believe in God because of drugs but rather that drugs take you to a different plane of existence, where there are entities who exist but on a different plane or different dimension. This is what he means by "the ancient teachers of mankind"-like these beings taught ancient man the secrets of civilization. It's a popular theory in archeological (?) circles that those who painted the famous cave paintings did so under the influence of certain substances. Hancock experimented with holy Ayahuasca in the Amazon and in his trip he saw a man with the head of a crocodile. He made the connection that some cultures had gods with crocodile heads and most certainly had anthropomorphic animal gods, a common sight when tripping on hallucinogens.
Interesting! Sounds similar to Carlos Castaneda. Those books blew my mind as a teenager. (when I was blowing my mind on medicinals..)
