Fact, that circles, and almost any other regular or completely irregular shapes in crop, certainly much more than 99,9999999% are generated by thanks to the lightning discharges, and not through some misguided self-declaring individuals, it is simply an objective fact, and mankind is able to detect objective reality after all (sometimes), it really knows how. (although this solves already well over 30 years and the results nowhere...)
