Alien Landing Pad
Geologists believe that the huge stones used to make the stone were originally in Preseli Hills in Wales approximately 137 miles away. Becuase of how huge the stones are it would be extremely hard for humans to move the stones 137 miles. Therefore there is a possibility that aliens would be able to carry the stones.

The theory is backed by many people who believe in aliens, there are many crop circles that have been found near Stone Henge, Crop circles are beloved to have a extra-terrestrial origin. Ley lines, possibly magnetic lines in the earth that connect "places of power" are often associated with aliens as well.
