For hundreds, maybe thousands of years, people have been trying to figure out how primitive people could build huge structures such as Stonehenge and the pyramids out of stone blocks weighing thousands of pounds. Scientists have been stumped. Then along comes a normal guy - a retired construction worker - and he says well, I would do it like this. And he does. This guy uses the simplest tools known to man and shows how simple and easy it would have been to create Stonehenge . This is a really great video clip. Amazing how this guy could figure out something that has confounded scholars for centuries. And not only figures it out, but demonstrates it! This guy could build a replica of Stonehenge single-handedly, while a committee of 20 or 30 Civil Engineering professors from leading universities would be debating how it might be done.
