I've been watching this series since it first aired in 2010 and been following the series faithfully. Having worked in the broadcast industry and studied ancient archaeology and anthropology since before Chariots of the Gods first was released and remember seeing the movie and reading the book first edition many times. I've always believed that many of these ancient stone age sites were much older than what current archaeologist state since It is scientifically impossible to carbon date rock structures.
I have extensively studied the prophets, both old and new from Enoch to Edgar Cayce and have personally been blessed by the power of prophecy. I was a member of the A.R.E.for many years and studied at the library in Virginia Beach, VA where I met Cayce's personal secretary Gladys Davis Turner who transcribed all of Cayce's readings.
Discovery Networks who owns the History Channel and the production company, Prometheus Entertainment have not shared with its' viewers many facts about ETV's on Earth (UFO's) and one of the primary sources of contact in the 20th century, Eduard Albert Meier (Billy Meier).
I am personally a witness, having my own UFO encounter in 1974 with missing time and believed that I was being contacted since I was a child.
Now, after fourteen seasons, I can't believe that your primary researchers such as Erich von Daniken, Giorgio Tsoukalos, Robert Clotworthy, David Childress, William Henry, Linda Moulton-Howe and many others have not come out officially in support of the incredible work, both photographic, in film and in writing that Billy Meier, a disabled, one-armed simple farmer living in Switzerland has contributed to the documentation of this field for over 50 years!
It's time that the History Channel, Discovery Network and Prometheus Entertainment enlighten other viewers who are less informed and educated than I about the truth from credible
Sincerely, JP
