What You Need for Stonehenge Is a Massive Number of Hands

What you need for stonehenge is essentially a huge number of hands. That would itself have been a damper on how long you could take to build it. And so the presence of these people, on the one hand, in the local community, is a huge pressure on resources. On the other hand, their absence from ther home communities is also straining existence activities back home. So this needs to be done as quickly as possible. Itt achieved stonehenge, it was doing something remarkable.
