Umm, the Nazi dream to dig up the secret and unknown all powerful Aryan civilization died with them dude. I would WAIT to see the actual dating, not the estimation of those ruins. And WHAT kind of buildings were they? monumental wonders like the pyramids? Or Stone shanties? Stone Henge by the way doesnt impress me. Small stone buildings rarely do. Pyramids on the other hand take planning that was so intense that we wouldnt be able copy thier work today or thier precision if we tried to using thier tools.
