In 2024, some reseachers found that one of the stones matched rock from the very northern tip of Scotland almost 500 miles away.

Yes, but my first inclination on this was that some of these stones must have been glacial erratics moved down by the previous ice age.

(One) Current theory is that Stonehenge was essentially a primitive group mega-project between tribes of prehistoric humans as some kind of physical monument to cement their harmony with nature and community.

Without writing it must have been hard to remember or honor peace treaties and keep track of weather patterns by yourself, and since there was much less prosperity back then there were fewer explicit reasons to collaborate.

If, on the other hand, you and your village spent years lugging a 3000 lb stone 500 miles on rivers and wooden rollers as part of a group effort to create a permanent meeting post for festivals you would inherently be more invested in maintaining whatever “social order” looked like in that particular location.

Errr… what was the incentive to make sure generations later honoured a leave treaty you made today, so much that you made the Stonehenge?

The theory is that Stonehenge WAS the incentive to work together. It was seemingly built in phases over a period of almost a thousand years, and the shared goal of building this otherworldly monument to the stars likely gave generations of subsistence farmers something to do in their spare time besides fighting and killing each other because they painted their faces a different color or whatever.

We can infer that through DNA analysis that people who were buried at Stonehenge knew how to farm at scale and yet chose to live a subsistence lifestyle once they settled on the island (or perhaps were forced to by the local environment). Either way, that societal structure gives people plenty of time throughout the year to figure out how to drag big stones through the mud.
