The Construction of Stonehenge
The thought that prehistoric humans had any kind of talent is unsettling to many modern humans for some unexplained reason. It may sound strange to put it that way, but consider the sheer number of people who are convinced that alien intervention was necessary for innumerable ancient sites. Yes, it's a fringe belief, but that doesn't make it unpopular. People actually believe that anything like Stonehenge had to have a mystifying beginning because of how it is impossible for people to move such large stones and arrange them in that manner 5,000 years ago without the aid of contemporary technology.
The truth is that because they were ignorant of current technology, ancient people didn't require it. So they found unique ways to resolve issues. Wally Wallington, a retired carpenter without an engineering degree, just utilizes rocks and common equipment to demonstrate that you can lift rock slabs weighing more than a ton using straightforward levers and stone pivots. To demonstrate that it could be done, he did it all by himself and constructed his own backyard Stonehenge. On a wider scale, with more people pitching in, it would have taken no time at all and been very simple.
