Crop circles are patterns created by the flattening of crops such as wheat, barley, rapeseed, rye, corn, linseed and soy.
The term was first used by researcher Colin Andrews to describe simple circles he was researching. Although, since 1990, the circles have evolved into complex geometries, the term circle has stuck. Various hypotheses have been offered to explain their formation, ranging from the naturalistic to the paranormal.
Naturalistic explanations include man-made hoaxes or geological anomalies, while paranormal explanations include formation by UFOs. However, researchers have pondered the question for several decades, but none have come up with a real answer as to why they exist.
And I also found an interesting face, seems most of the crop circles are existed in UK. lol
