If You Find A Crop Circle, Call A Cereologist
Cereologists get their title from the Roman goddess of agriculture, Ceres. Not all of them agree about what causes crop circles, though they do acknowledge that many are the work of pranksters. The rest, they argue, could be the products of extraterrestrial activity, plasma vortices, or even the consciousness of planet Earth. Some of the more intricate crop circles are based on mathematical equations, while others are simple circular patterns. One of the more scientific theories postulates that crop circles form when natural vortices of wind flatten the crops. However, most professionals believe that crop circles are 100% manmade.
