Quote from Weyland:
"We have the cave paintings at Lascaux (along with a variety of artifacts found in there too) dated to around 30,000 years old,

In fact, if you like paleolithic art and constructions, here's a good site:
http://witcombe.sbc.edu/ARTHprehistoric.html#paleolithic
So, what'll it be: Are these sites all incorrectly dated, are they fakes, or is it possible that mankind is a wee bit older than 6000 years? Inquiring minds want to know."
I had a quick look but didn't see anything on the method used to date these constructions. But like most forms of dating these days, it is more than likely highly inaccurate.
This is a good artical carbon dating, and other forms.
Doesn’t Carbon-14 Dating Disprove the Bible?
