Crop circle mythology is still going strong, as TV viewers will attest, even though the strange formations have long been exposed as a hoax. It all began in the English wheat fields in the late 1970s, when UFOlogists and other paranormal researchers became convinced that crop circles appearing out of nowhere must be messages from aliens or other equally strange phenomena. Finally, in 1991, two pranksters named Doug Bower and Dave Chorley owned up to having created the circles using planks, rope, hats, and wire as their only tools. Their method still continues to be duplicated. Though the process has been explained in countless television shows, many still choose to believe they're products of alien life.
