Crop Circles

The earliest crop circle was found in Scotland in 1647. In 20 century 80s, British discovered many crop circles in the wheat field. Therefore, the phenomenon was called crop circles.

Many people believed that crop circles were made by aliens. It is reported that many places where lots of crop circles took place frequently may appear UFO. Besides, the crop circles made by human being were rough and the wheat couldn’t continue to grow up any more. However, some crop circles were so perfect that it is impossible to make by human.

In addition, some people considered that crop circles were just made by human. Moreover, crop circles became tourist attractions, which promoted local economic development. Therefore, some people think crop circles were made by British government to increase the income.

Besides, some people thought that crop circle was just a natural phenomenon. It was made by tornado, magnetic field or radiation.

In my opinion, I believe that crop circles are made by aliens. Because some crop circles are so perfect and amazing that we human couldn’t make in such a short time. We couldn ’t make sure who made the crop circles yet, however, with the development of technology, we will find out the truth.
