I've recorded it as missed some of it. I did see the bit about Grimes Graves and was puzzled that Easton Down Flint Mines weren't mentioned (maybe I missed that bit) as just a few miles from where Salisbury now is I would have thought the flint used by the Stonehenge people would have come from there. One of the presenters also implied that adolescents went down the flint pits as a rite of passage. I don't think that would have been the case anymore than it was for young people going down the coal mines in the good old days of more recent times. More likely they were slaves.
