Crop circles? What exactly crop circles mean. Is it a design that aliens made or just some design done by the genius? The theories behind the crop circles are more it existence.

Definition:
A crop circle is a sizable pattern created by the flattening of a crop such as wheat, barley, rye, maize, or rapeseed. Crop circles are also referred to as crop formations, because they are not always circular in shape. The documented cases have substantially increased from the 1970s to current times. In 1991, two hoaxers confessed and claimed authorship of circles throughout England. Crop circles are another of these mysterious phenomena that intrigue scientists, mystics, and the general public alike because their appearance is unexplained. Crop circles have been around for a while, but became most popular when a number appeared in England in the 1970s and 1980s. New crop circles have appeared every spring and summer. A crop circle is an area of a field, usually planted with wheat, corn or other such crops, which has been flattened in sections that form patterns when viewed from the air. These patterns are large, complex, precisely made, and generally appear overnight without anyone seeing them being made. This has, quite naturally, led to speculation about their origin being paranormal at least if not alien, made by extraterrestrials visiting us in their UFOs.

History:
A The concept of crop circles began with the original 1970s hoaxes by Bower and Chorley. They were inspired by the Tully "saucer nest" case in Australia, which can be taken as an early case of crop circles. There are pre-1970s reports of crop circles, but they were always simple circles, which could have been caused by whirlwinds.

Early reports:
In 1686, British scientist Robert Plot reported on fairy rings in his The Natural History of Staffordshire, and said they could be caused by airflows from the sky. In 1991 meteorologist Terence Meaden linked this report with modern crop circles, a claim that has been compared with Erich von Däniken's pseudohistoric claims.
A 1880 letter to the editor of Nature by amateur scientist John Rand Capron, describes how a recent storm had created several circles of flattened crops in a field.
In the 1960s, in Tully, Queensland, Australia, and in Canada, there were many reports of UFO sightings and circular formations in swamp reeds and sugar cane fields. For example, in 1967, a group of circles appeared in a field in Duhamel, Alberta, Canada, and the Department of National Defence opened an investigation. The most famous case is the 1966 Tully "saucer nest", when a farmer said he witnessed a saucer-shaped craft rise 30 or 40 feet (12 m) up from a swamp and then fly away. When he went to investigate the location where he thought the saucer had landed, he found a nearly circular area 32 feet long by 25 feet wide, where "the grass was flattened in clockwise curves to water level within the circle and the reeds had been uprooted from the mud". The local police officer, the RAAF and the University of Queensland concluded that it was most probably caused by natural causes, like a down draught, a Willy-Willy, or a waterspout. In 1973, G.J. Odgers, Director of Public Relations, Department of Defence (Air Office), wrote to a journalist that the "saucer" was probably debris lifted by the causing willy-willy. Hoaxers Bower and Chorley were inspired by this case to start making the modern crop circles that appear today.

Madvision View:
Well, I believe in aliens, yeah its true that we are not alone here in these universes. Their existence is true. If they are visiting our home planet than it means they are very intelligent with the hi-tech facilities. It’s a simple logic, Here on earth we are now doing so much improvement in our science and technologies, but besides that we still can’t visit to other living planet. So, think if those aliens are visiting here than how much advance they are.
But, seriously ? The highly advance aliens are coming from many light years to make some kind of stupid designs on crop farms. It’s really making my mind crazy. Is our corps being their drawing boards :D? There are many questions related to the CROP CIRCLES. The answer is also so many which is true and which is false its very difficult to judge.

Keep thinking…. Madvision.
