One of the most widely known extraterrestrial phenomenon, crop circles have appeared in fields all of the world. With their meanings having been theorized to be either means or communication or simple where their ships propulsion systems leave marks, no one truly knows why they are left. Crop Circles are considered to be extremely controversial due to the fact that it is possible to make one. However, some people who say they have witnessed such crafts touching down claim to have gather evidence to the contrary. Crop Circles in general are wildly speculative and are considered to be the orbs of Ufology.
What are your thoughts on crop circles? Intergalactic tweets of simply some people yanking chains with advanced vandalism?
