A crop circle is a pattern created by the flattening of a crop such as cereal, rapeseed, reeds, grass. They are also referred to as crop formations because they are not always circular in shape. Some cerealogists say that these diagrams must be created by intelligent alien beings from elsewhere.
One of the most interesting circles to appear in recent years is at Milk Hill, Alton Barnes, Wiltshire that has been named 'The Galaxy'. This particular circle comprised of more than 400 circles, perfectly aligned in a psychedelic swirl.
Although many of todays crop circles are known to be the work of pranksters, interest in crop circles has enjoyed a recent revival because of a pair of new patterns that appear in a field next to the Chilbolton Observatory in Hampshire, England.
One is of a face, that could be interpreted as looking similar to the face of a "gray" alien.
The second is a modified version of a message that was sent out into deep space in 1974 from the Arecibo satellite dish in Puerto Rico, broadcast in the direction of the globular cluster M13 in November of that year.
This was the crop circle. The original message was:
Now the comparison between the original sent message and crop circle is:
Another thing to take into account is the way that the 'ET Message' shows that thier DNA structure is very similar to ours.
Scientists have also found a change in Magnetic field where Crop circles are found. In many places before formation of crop circles, UFOs are seen.
