How did crop circles appear?

Crop circles are almost as well known as Bermuda Triangle, but the mystery of crop circles seems to be more difficult to solve than Bermuda Triangle, which is considered to be the wreckage of planes and ships invented by a group of novelists and frogs at the bottom of the well. Not every crop circle can find the culprit behind it, and some of them have been proved to be natural phenomena, not man-made, so it is difficult to distinguish between true and false. At first, people naturally thought that it was done by aliens, or that wheat had its own wisdom, but as time went on, things became even more "wrong" Crop circles are thought to have started in Hampshire and West End of London in the early 1970s, and then spread around the world like a virus. In fact, crop circles were recorded as early as 1678. Because no one can explain their formation, the "devil who harvests wheat" took the responsibility.

At first, these crop circles were just simple circles, single lines or patterns, but in the 1990s, the design of crop circles became more and more powerful, and each crop circle even had its own name, such as "Galaxy", "Alien Portrait" and "Chemical Element". By 20 12, even the "mother of crop circles" appeared. There are so many strange crop circles that it is not without scientists investigating outside. As early as 1989, a group of scientists launched Operation White Crow, promising to find the culprit of crop circles.

Operation White Crow lasted for 10 days and monitored crop circles 24 hours a day. The research team of 25 people includes meteorologists, physicists and scientists, who measure and analyze weather anomalies and other strange things. But this time, they didn't catch anyone and were warned by the military. Some people in the team also experienced unexplained hallucinations and sounds, but they took strange photos of white flashes and "strange positions" of straw in the sky. Coupled with the obstruction of the military, Britain has become the focus of public opinion, and the number of tourists has increased dramatically.

People have to pay to see crop circles. So some people say that this is a conspiracy of the British government to promote the development of tourism; Others say that aliens created crop circles, and the truth has been classified as a military secret. 1990, frustrated scientists changed "Operation Bai Niao" to "Operation Blackbird" and started another investigation. This operation lasted more than half a month, and crop circles were really discovered. However, when the investigation team arrived there, there was no one in the crop circle, but there were fortune tellers, wooden crosses, red ropes and other tools. This proved to be man-made.
