The crop circles were first been found in late the 1970s. There are couple theories of the exist of the crop circles. Some people say that they are made people, and some people state that they might be made by extra terrestrial.
In the 1990s, scientists found that 70% of the crop circles were made by people whose purpose is to attract the tourists. All the mystery seems has been solved. However, in the late 1990s, people noticed that some crop circles were suddenly appear in one night. The gorgeous special patterns show on the crop field made people come back to explore them. The scientists were trying to fine the people who made those crop circles; however, no one shows up in the next half year. Some scientists tried to make a crop circle. They used all the most advanced machines to create a crop circle as fast as they could. However, the difficulty of making a crop circle made scientists feel frustrated.

There are still 30% of the crop circles are still the unsolved mysteries. The most persuasive theory is that the some crop circles are made by alien. Probably those are the massage they send to the Earth.

I've heard a lot of stuffs about the crop circles before. Some of them are really mysterious, but some of them are just made up. I think thats not alien, they might be caused by the magnetic field!
