If its done at night with out the aid of light, then how can man be that precise with crop circles that are sometimes as large as eight football fields? Also what do you think Deep Dasgupta about the prime numbers in crop circles? Do you think its just coincidence that I have found more then several to be prime? You mentioned microwave residual left in the crop circles; I believe that spaceships which have an uploaded image of a crop circle hover over a field and microwave blast it in sections to lay down the crop circle. Also the ship may cloak and would have infrared detectors to make sure humans where not in the area at the time of forming the crop circle. A spaceship with a 30 yard diameter could hover at 8 feet above the field and lets say the cook time is 2 minutes per section; A ship that hovers with that kind of technology could do a 8 football field crop circle in about an hour and half and thats only if there is one spaceship.
