I first became aware of the author (Michael Cremo) after hearing him talk on American radio station "Coast to Coast AM" via Youtube.
I'm adding to the previous reviewers' text.
The book comprises archeology, spirituality, genetics, quantum physics, the origins of humans and possible alien intervention (millions) of years ago. The author also provides solid proof of the human devolution and related subjects.
Anyone interested in archeology/paleontology should pick this book up, you might be shocked to read what the mainstream is not telling.
Most of the pages are devoted to case studies, but I found that there was just too many case studies. Easily 10 per subject. I found myself skipping some pages.
This is also a good introduction to spirituality and if you have been reading what you where taught at school/church, this book would be an eye opener.
Excellent work :))
