The series of boulders that make up Stonehenge have long puzzled experts and provided material ripe for conspiracy theorists.
Most pertinent is the question: how were the stones - some weighing 50 tons - transported and arranged to where they sit today?
Without basic transportation technology, such as wheels (which were invented more than five centuries after Stonehenge is believed to have been built), there is no obvious answer to how the biggest stones were moved.
Much of what scientists do know about the construction of Stonehenge is from educated guesses and constantly evolving research, the newest of which suggests that in fact two of the largest boulders that make up Stonehenge have always been “more or less” where they sit today.
Alternatively of course, scientists could shun the research and read Erich von Däniken’s seminal book Chariots of the Gods?, “which makes the argument that many ancient megastructures such as Stonehenge, the Egyptian pyramids, and the Moai heads of Easter Island were built using know-how passed down from God-like aliens to mankind”, says The Independent.
Though why the extraterrestrials would pass on the knowledge of how to build Stonehenge but not the wheel is anyone’s guess...
