Crop Circles - formations, usually found in grain crops, where the crop has been mysteriously found laid flat, in patterns, that did not exist in daylight the previous day. Although thought by many to be a phenomena of the 20th Century, crop circles and formations have been around for a very long time, and records even date back well before the invention of the camera.

Twenty-six countries ended up reporting approximately ten-thousand crop circles, in the last third of the 20th century, and 90% of those were located in southern England. Many of the formations appearing in that area are positioned near ancient monuments, such as Stonehenge.

Formations usually are made overnight, but have also been made during the day. The most widely known method for a person or group to construct a crop formation is to tie one end of a rope to an anchor point, and the other end to a board which is used to crush the plants and the most well known positive depiction of a crop circle is found in a woodcut made in 1678 with the title 'Strange News out of Hartford-shire’. It depicts a devil-like creature cutting out a pattern in a crop with a scythe.

Interesting fact if we know that "Our Visitor" made it. According to Suzanne Taylor, Writer of What on Earth (Inside the corp circle mystery) book, Why would our visitors be making crop circles instead of doing things that would be helpful to us?, If sending circles is their hello, they could be awaiting an aha from us, where we get it that they exist. Then we would invite them in rather than fighting them off.
