crop circles
TRANSCRIPT
Crop circles is a term used to describe patterns created by the flattening of crops such as wheat, barley, canola (also called "rapeseed"), rye, corn, linseed and soy.
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.
Many circles are known to be man-made, such as those created by Doug Bower, Dave Chorley, and John Lundberg,
The Circle Makers: The most famous group of crop circle makers, founded by Doug Bower, Dave Chorley and John Lundberg.
