Most people need concrete evidence to believe in the reality of extraordinary phenomena. This is perfectly understandable in a world where we are taught to believe only in things measurable with physical devices under controlled conditions. The reality of the Crop Circle phenomenon is not dependent on such evidence, but the presence of the evidence increases its credibility. If some individual crop formation displays no evidence against human creation, this formation doesn't become less real as a result of such finding. We must not allow ourselves to think that each formation that COULD be man-made (in the light of physical evidence) automatically is.

Instead, its more reasonable to think that each formation that COULD NOT be man-made (at least not by stomping), is not. Only we must not too easily jump into this kind of conclusions. It is also reasonable to conclude that a formation is created by stomping if it clearly looks that way. Of course in this case the formation must be evaluated soon after its creation, before visitors leave their marks.

In the following I will list several individual features which talk in behalf of a non-man-made phenomenon.
