I stopped reading about halfway through the second link because of how absurdly propagandistic it sounded.

The fourth one does refer to him briefly as one of the people pushing for the initial expedition, but on the other hand cites carbon-testing from two different institutions resulting in an average date of 6500 BC.

With a little more digging, I also found a New Scientist article from the original 2002 find.

So, yeah. That answers my question.
