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

Hmm, the site linked to says 15000-17500 years old for Lascaux. Though elsewhere it does give information about other cave art (such as
Chauvet-Pont-d'Arc) that is 30000 years old. Mind you, 15000 is old enough to disprove the original assertion that there's no evidence for humans before 6000 years ago.
In addition to the 14C dating of the pigments, the Lascaux paintings also include depictions of constellations that were particularly prominent in the sky 17000 years ago.
