Our ancestors needed a sense of place to think about erecting anything of any permanence.
If you are a hunter gatherer tracking the herds of reindeer using what became the Ridgeway along the southern edge of a retreating ice sheet, you might revisit places each year for annual crops, (potentially hazel nuts), you aren't anywhere long enough to build more than a temporary structure.
Agriculture anchors (proto-/neo-)humans to a place.

Agreed, but our understanding of the chronology of human achievement is limited by what has survived through the ages. Prehistoric does not mean rudimentary: Göbelki Tepi predates Stonehenge by 5000 years. More time passed between the time that site was active and flourishing and the construction of Stonehenge than between Stonehenge and now, and we have no idea who built (the much more complex) gobelki tepi or how or why.

Thing is, we know next to nothing about the people who built it, let alone their technology. Modern views are that they were primitive and only had the most basic creations we can imagine, the likes of which weren’t even invented by our species but by a preceding ape (homo habilis made tools 2 million years ago, neanderthalis made elaborate clothing and jewellery to decorate their dead in complex funeral rites tens if not hundreds of thousands of years ago).
We believe homo sapiens sapiens has been physiologically pretty much the same for a couple hundred thousand years now. Was it really only a few thousand years ago that humans got creative and industrious enough to create wooden machines to lift things?
Not directed at you personally, but modern archeological convention strikes me as having a Victorian attitude to science, equating a (perceived) lack of cultural sophistication with an actual lack of cultural sophistication.
