I've just finished listening "The Ancient Alien Question" by Philip Coppens The Ancient Alien Question: A New Inquiry Into the Existence, Evidence, and Influence of Ancient Visitors: Philip Coppens, Erich von Daniken: 9781601631985: Amazon.com: Books audiobook. My take is that it deals with the subject more objectively and in a more balanced way than the History Channel does in its famous series. I highly recommend the book for anybody who has an interest in this area.
