Crop Circles

Crop circles have been associated with aliens for years. Many people believe there is no explanation of why, and some have gone as far to say that they are symbols marking where to "attack" or that aliens are trying to communicate with us through something that are similar to hieroglyphics. They appear often on television shows about aliens, and are mocked in Scary Movie 3.
These crop circles are flattened parts of a crop field showing huge pictures. In 1991, two men confessed they had made several crop circles over decades to trick people into believing in alien life. However, even though these men admitted it, many people are not convinced because these sightings have been all over, and some believe these two men just wanted fame. this is the mock one from scary movie 3
this is allegedly real.
