"with the dates in the British Isles also being pushed further backwards, it's going to make Stonehenge (ca 2,000 BCE) look one day like a relic of the Modern Industrial Age".
Howdo AQ
You're going to have to include Stonehenge in those pushing back of the dates. The four post holes/pits that were discovered about 100 meters east of the stones, which almost certainly had to have had a ritual function, have yeilded a radiocarbon date spread of between 8500 and 7650 BC.
