Crop Circles are pattern formations that occurs on crops such as wheat, barley, or rapeseed. These patterns tend to be circular in structure, but not always.
These bizarre markings are considered extraterrestrial in origin by many people. It is believed that these symbols were made by extraterrestrials during one of their expeditions to Earth. According to several ufologists, these symbols were actually messages that aliens left behind, and they are speechless as to what these messages mean. They are also clueless as to whether or not these supposed messages are of a good or bad nature.
Those of a more critical mind, however, considered there to be a scientific explanation for these strange patterns. Many propose that these patterns were most likely created when a tractor malfunctioned, and it could only make right turns through the fields. According to them, this awkward occurrence would ultimately lead to a circular formation in the crops, thus leading to a crop circle. Others believe that some crop circles were faked by people seeking attention.
