Turkey, 1995, a site was discovered that made archeologists reevaluate their theories about the Neolithic revolution. But could they still be wrong?

In Britton, France, there’s fields of standing stones. Could there be a connection to Greece or maybe even further away?

A Latvian man builds by himself a large castle, some speculate that he learned how by unlocking knowledge that was handed to the ancient Egyptians. Could this trail lead us out of this world? 

Our host Fredrik continues the mission to discover what is genuine, fake, and somewhere in between on the TV-show Ancient Aliens. In this episode we will break down episode 8 from season 2 (S02E08) called “Unexplained Structures”. This episode will take us across the globe, exploring places and buildings that the show claims modern science can’t explain. 

To see if this is true we have with us Dr. David S. Andersson who is an expert on Mayan civilization. He has also been writing in magazines such as Forbes Science, Washington Post and AiPT to name some. David will also have a chapter in a new book called “Comics and Archaeology” where he will participate with a chapter on pseudoarchaeology and American comic books. You can read more about that project right here. If you wish to know what else Dr. Andersson is up to you should follow his twitter @DSAArchaeology
