Crop circles

Crop circles are complicated geometric patterns, usually in wheat fields. Some people believe that the patterns are left by the imprint of an extra-terrestrial craft, or that they are by the imprint of an extra-terrestrial craft, or that they are a message from extra-terrestrials themselves. Another theory is that natural forces such as tornadoes, heat or strong winds create the patterns by flattening the crops, but the regular shapes of most crop circles makes this unlikely. The most likely explanation is that the crops are made by people as a hoax. They gradually build up a design by flattening the wheat, using very basic equipment such as rope and planks of wood. Those rose in fame in 1975 as circles began appearing all the way through the English countryside. In late 1980s the phenomenon of crop circles turns out to be widely known widely. A farmer in 1996 set up a booth and charged a fee for visiting the crop circles which appeared near Stonehenge. The value of the crop been harvested by him was most likely of about 150 pounds, whereas he collected 30,000 in four weeks.
