This is Why Stonehenge is Such a Big Deal
Well, it’s the right shape for a flying saucer… History Extra

2. Some people think that Stonehenge was built by aliens

Amongst the most controversial and, frankly, stupid historical schools of thought around today is the ancient aliens theory fanously propagated by the History Channel. The ‘logic’ behind the theory is that ancient people were not intelligent or technologically-advanced enough to build such things as the Pyramids or Teotihuacán, and so it must have been aliens. The problem with this theory is that it not only presupposes the existence of extraterrestrial life, but assumes that aliens had the inclination, biological capability, and technology to visit Earth. It also overlooks centuries of academic research and some great stories of human achievement.

But we have to look at the ancient alien theory about Stonehenge, as it’s disturbingly widespread. Acknowledging the astronomical significance of the monument, some people argue that knowledge about the heavens must have been given to prehistoric people in Wiltshire by aliens. The mystery of the Bluestones can be explained by aliens using their vessels to move them from the Preseli Hills, and the circular form of Stonehenge made an ideal landing-pad for their space ships. The only thing out of this world about Stonehenge however is the level of effort, knowledge, and sophistication required to build it.

1. Whoever built it had a phenomenal knowledge of astronomy and mathematics

Discounting the above for obvious reasons, there are many convincing theories about the function of Stonehenge. Burial ground, ceremonial site, temple, astronomical calendar: it is all of these things at once. But a final, mind-blowing thought before you go: the people who designed Stonehenge had an incredible knowledge of astronomy and mathematics. Aligning the stones to the precise location of the sun rising at the Summer Solstice and setting at the Winter Solstice would have required years of observing the skies. Given the various stages of building and redesign, this was not the work of an individual or a fluke.

Research published in 2005 also sheds light on the advanced mathematics behind Stonehenge. The landscape archaeologist Anthony Johnson used computer analysis to determine that the chalk pits around it form a 56-sided polygon, laid out using square and circle geometry. The builders first used a rope to mark a circle, then laid out two squares to make an internal octagon, and from there the huge polygon was formed. This is all evidence of significant planning and knowledge, and erecting the stones would have required calculations on weight and the angle of the surface. All this, 2, 000 years before Pythagoras…
