Crop circle

A crop circle or crop formation is a pattern created by flattening a crop, usually a cereal. The term was first coined in the early 1980s by Colin Andrews. Crop circles have been described as all falling "within the range of the sort of thing done in hoaxes" by Taner Edis, professor of physics at Truman State University. Although obscure natural causes or alien origins of crop circles are suggested by fringe theorists, there is no scientific evidence for such explanations, and all crop circles are consistent with human causation.

I think not! There is way too much evidence, beauty and precision for a human to make something like that. Acceptable but who did? And what does it mean? That is open for discussion because I've heard that they are invisible energy patterns sent from somewhere outside Earth. I do know that it is a cross section of a 3D image though...
