How this man has managed to write so many books while knowing nothing about 1) travel and 2) archaeology is a mystery to me. First he shows up in Jordan with no local money on a Friday (you'd think someone passing themselves off as a knowledgeable traveller would have figured out banks in an Arab country are closed on the Muslim sabbath) Then he continues on with a series of quack theories about aliens, and technologically advanced ancient civilizations, and harps that make rocks float. There not even good quack theories, like Hancock or Buval (who, while equally worthless, at least make an attempt to back up their theories) Read something else.
Answer:
Negative
