Here is an article from England in 1678.... thats right 1678. And back then there were no planes to fly overhead and get the jist of the actual cirlce. In this article the farmer claims to have lost half an acre... that a big cirlce.
Tell me if this is a description of the Devil mowing down the oats, or a crop cirlce... Oh and there are plenty more that go back so far that it would seem impossible for the creators of these circles to been humans. And never taking credit for it. The admitted circle makers circle's are a joke compared to real ones... It's just another exmple of Man imitating nature. It real... and I think that frightens peolpe... so they dismiss it... it's easier that way.
