Yes I saw this.
I haven't been too impressed with the series so far - Spivey seems to be hell-bent on publicizing his ideas without a great deal to back them up. I was a bit worried, for example, when he stated that the Amesbury Archer was from the continent and was probably responsible for the building (shouldn't that have been the rebuilding?) of Stonehenge. If the Amesbury Archer was from the continent (and I accept the fact that tests on his remains may have proved that he was) it doesn't answer intriguing questions such as why he made the arduous journey to Britain in the first place and why he went, and was eventually buried, on Salisbury Plain.
Perhaps those questions will never be answered but perhaps it's also too easy to assume that, because he was from the continent, he or his family were not originally from these islands. We should not dismiss the idea that the Amesbury Archer could have been the child of a noble or priestly family who originated from the area around Stonehenge and, for some reason, travelled aboard. Perhaps the Avebury Archer was returning to his homeland...
