Alien Agenda By Jim Marrs By halcamdad on Sep 21, 2007 - Updated Oct 15, 2011

This is an intriguing book about extraterrestrial life??? Marrs explains the nature and his theorized origins of mysteries such as crop circles, cattle mutilation, military conspiracies regarding aliens. Much of the material presented in the book is supposedly taken from hitherto hidden, confidential governmental files (hard to believe, you'll have to form your own opinion as to the authenticity of what's presented.

Marrs moves through the history of extraterrestrial theory interjecting his theories along the way. I really believe that Marrs is extremely intelligent and well-learned in his field, but I couldn't get past his biases. I found this book to be very interesting and thought provoking. At the same time, I was suspicious about many of Marrs' proposed explanations.

Definitely worth the time if your intriqued by the possibility of alien existence.
