Göbekli Tepe

I've just heard about the archaeology going on at Göbekli Tepe, located in Turkey. The monumental Neolithic (!) architecture at this site dates to 10,000 B.C. at least. Not exactly Bishop Ussher's 4004 B.C., 'ey? The crackpot religious/ancient aliens rumor mills are churning overtime. Personally, I think they look like particularly primitive crop circles ;-)
