I'm new here .. nice place!
The ancient alien theory in my opinion is an interesting subject. I appreciate Xaviants wide perspective, presentation and easy read. In my opinion Xaviants book represented many views of ancient alien theorists. Asking questions as to our origin and presenting alternative ideas is not a crime and the question does not require scientific reinforcement. The answers are what require scientific reinforcement.
Xavient presented the ancient alien theory and an argument.
Let's hope his book inspires others to engage in the science and the history of these lost and found civilizations.
