Crop circles are the crop formation of patterns created by the flattening of a crop at an equal height,[1] usually a cereal. The term was first coined in the early 1980s by Colin Andrews.[2] The worldwide phenomena is of interest to ufologists and alien hunters to determine if alien intelligence is communicating with humans through concentric patterns.

Alien communicationEdit

In ufology, crop circles are 'alien calling cards,'. Ufologists say that crop circles are either imprints from an alien spacecraft or messages from aliens to humans. One of the most famous crop circles is the Arecibo response (See The Arecibo Files).

Earth energyEdit

There are claims that an energy emits from crop circles. Some researchers have measured magnetic fields inside the crop circles, and visitors have reported a tingling feeling when standing inside them.


People can hoax crop circles by simply going into a field and flattening plants themselves, usually with a wooden plank or similar instrument.

Puede engaño círculos de las cosechas, simplemente entrar en un campo y aplanar las propias plantas, por lo general con un tablón o similar instrumento de madera.

Hoax crop circles can easily be spotted by the flattened track of somebody entering the field, damaged plants, and a often simple and small shape.

Hoax círculos de cultivo puede ser fácilmente detectado por la pista plana de alguien entrar en el campo, las plantas dañadas, y una forma a menudo simples y pequeñas.

and police may often deliberately intend that crop circles are hoaxes, in effort to cover up alien evidence.[3]

Los gobiernos y la policía puede a menudo deliberadamente la intención de que los círculos de cosecha son bromas, en un esfuerzo por encubrir la evidencia


Cerealogy is a limited term to convey the study of certain Crop Circles,[4] namely that of cereal crop.
