knowing some elementary astronomy goes a long way in understanding why these sites (stonehenge, the egyptian pyramids, and other pyramids in central america, etc...) were built that way.
Today we underestimate the "human potential" to construct these sites.
The pyramids were built by thousands and thousands of workers over the course of several decades. The great wall of cina is the same, milions of workers over the course of centuries. That wall was built just using raw manpower. No need to call in the aliens to explain its existence.
