Crop CirclesThe crop circles first appeared in England. They are areas in a field of corn or wheat that is flattened in an artistic fashion. Usually the pattern contains circles of various sizes. People began to credit spacecraft aliens for the creation of these patterns. The media just loved this one. They still show newly created crop circles and leave the viewer with the notion that they could have been produced by aliens.Claims are made that the area of the flattened crop gives off an electromagnetic radiation that is unnatural. The claim is made that this same radiation has been detected at the location of UFO sightings. The area is damaged to the extent that the pattern shows even after several plowings. Others claim the crops show evidence of strange mutations in the downed plants.
