Are crop circles created by extraterrestrials or hobbyist hoaxers? The fact is, there have been over 6,000 crop circles documented since 1980. Analysis of cellular structure of the plants from many crop circle sites reveal that the composition of the plant material has been greatly altered. Split tests with complex geometrical crop circles and that of known man made crop circles have revealed a discrepancy in the chemical composition.

So while there certainly are faked crop circles, many are unexplained - and a unique few are absolutely intense. Here are 55 of the most intense crop circle photos ever taken.
