The earliest known formation was in 1647 in England, from which a carving (see below left) of the current day theory on how it was created can be seen. Yet, they began to appear in significant numbers in the early 70's as individual circles that swired either clockwise, or counter-clockwise. A major transformation occured in 1990 when the circles became complex pictograms composed of straight lines, angles and spiral rings (see Barbury Castle formation below right).
There are many various theories of how these images are formed, but the mystery is far from being solved. Many people attribute them offhandedly to hoaxers without being aware of the complexities that are characteristic of genuine formations. And those who associate them with UFOs often believe that their reality is as debatable as those little green men, but as you will see here... they are very real. The best way to verify this is to physically stand in a crop circle yourself.
On this web page, you will see compelling reasons for why the entire crop circle phenomenon should not be simply dismissed as a hoax or science fiction. It's by no means a complete reference source, but rather an introduction to the world of crop circles that hopefully will ignite a spark of curiosity in everyone who visits Crop Circle Central.
