I've been a fan of Cremo for some time. Some of his ideas are a bit loony, but he does talk of some interesting archeological finds. Archeologists (and science in general) too often ignore things that dont fit into their theorys. I say that as someone who is a big fan of science and understands the scientific method. Modern science is like the "dark ages" was for religion but with less torture. Instead of torturing heretics, they torture data and ridicule dissenters. See AGW.
