Actually Tsoukalos does not say that aliens built the pyramids, but he does assert that ancient man built them with the help of “alien technology” & blueprints. One thing he stated which stands out was his jarring & astute question: “where are the blueprints?” [ to the pyramids ] One would think that such a massive undertaking would have originally started with a blueprint. No modern day architect would ever construct a building without first creating or drawing up a blueprint first.
