Why is it suprising that some of the stones from Stonehenge travelled 200 miles?

It's surprising that some of the stones from Stonehenge traveled 200 miles because they come from the Preseli Hills in Wales, which is an impressive distance for prehistoric people to transport heavy stones without modern technology. The effort involved in moving these massive stones over such a long distance raises questions about the significance and purpose of Stonehenge, suggesting advanced planning and organization. Additionally, it challenges previous assumptions about the capabilities of ancient societies in terms of engineering and logistics.
