Very interesting.

Sometimes when I mention ancient civilizations that predate Biblical history peoples eyes glaze over and quit listening, or they simply brush off scientific evidence as being incorrect or question the method of dating all together.

We'll keep discovering more evidence that dates mankind back tens of thousands of year, but some people just are not ready to accept alternative theories on history.

This certainly is a fascinating find. It's rare that one finds remnants of similarly old civilizations. Hopefully, similar finds will help explain why our various civilizations seemed to rise very abruptly in the recent past. Perhaps there wasn't that much of a gap between the recent past (approximately 4-6,000 years ago) and the distant past -- 10,000 BC and before.
