In Turkey, they've found an absolutely amazing site:
It's an ancient temple, possibly the very first one, at least on a large scale, dating back about 14,000 years. This thing makes the Pyramids look positively youthful.
It's really set archaeologists on their collective butts; it adds a great deal of weight to the theory that religion begat civilization, rather than the other possible explanations. Brewing and agriculture have been two leading lines of argument, but this temple precedes all known examples of those; in fact, it appears to predate writing. The general thought has been that temples were a symptom of humans settling down; this site implies that temples may have been the reason for that, not a symptom.
