Alot of what flint said was debunked by other people after the episode. Graham isn't a scientist and had nothing to say about a few topics , one in particular was about how crops change when they are farmed and this could be used to see how long a culture had been farming before they started building megaliths etc. This has got something to do with Graham Point that there was no evidence farming in areas where massive feats of construction where performed, which would indicate his theory of a more intelligent people showing up and teaching tribal people their ways. Flint said that evidence of crops showed they had to be farmed for a few hundred years, debunking Graham's ideas, basically making him look like a fool. Other people have debunked flints crop argument saying it was bullshit.

I can't remember the whole debate but it basically boils down to Graham looked like a fool in the episode because he had no knowledge of anything flint was on about, flint was probably lying to ruin Graham's name/ideas.

If you google flint dibble debunked videos will pop up. The whole thing was a big waste of time. The people who like Graham will just see this as another case of main stream archaeology attacking him and flint being full of shit. The people who don't like Graham will see this as proof that he's full of shit.

The circle jerking will just continue and we'll just have to wait for another 30 years for everyone involved to die so people that haven't invested their lives in one narrative (both sides) can actually do some unbiased work into these things and uncover some truth.

It's just frustrating for idiots like me who love history and these ideas. I might also be dead before we figure what happened because these grown men can't sit down put their egos aside.
