Most, if not all, crop circles are probably due to pranksters. For example, Doug Bower and David Chorley admit to hoaxing approximately 250 circles over many years.

Skeptics have long known how a small group of hoaxers can easily produce a crop circle. The two circles we made in recent weeks are valuable hands-on experiments that take CSICOP beyond the realm of mere armchair debunking. We learned that domestic grains like oats are better than wild grasses. We also better understood just how quickly patterns can be made with simple implements—all of which can be carried over one's shoulder and in a backpack. The tools necessary to survey the geometry are no more complicated than a length of rope. (We used a tape measure, but that could easily be eliminated by marking certain lengths on a rope with colored tape.) Finally, after trampling down both crop circles on hot summer days, we recognized yet another reason for performing such hoaxes in the cool of the night with flashlights.
