I was reading that they estimated the lower enclosures to be 15,000 years old! Mind blowing.
What gets me is that they could do such fantastic and accurate structures, which leads me to believe they had to have had practice. It is rare that people could get this right first time round... I guess I am suggesting there may be earlier sites knocking around beneath the hills of Turkey.
