What are crop circles caused by?

By people, as has been documented extensively. We have known that crop circles were man-made since at least 1991, but twenty-one years later people still look for more fanciful explanations.

One of my esoteric teachers told me once that real crop circles aren't made by aliens, but by some unseen forces of nature and they act as acupuncture for planet Earth. So they have nothing to do with aliens or UFO :).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
