I believe in a lost advanced civilization just as Atlantis that may have been global or at least had global connections, but that Tartaria theory is nothing more than the Flat Earth Theory. Tartaria was real and was the western/latin name for the last vestages of Gengis Khan's Mongol Empire. The real Tartaria had nothing to do with architecture nor being a global society. The real hidden history is the pyramid builders and the pre-flood civilization, that is the history that has been kept from us and it is much much more ancient than the disinfo Tartaria nonsense.
