Crop circles are in fact an effect of completely natural origin. Meteorology, physics, chemistry, biology. The plants were hit by the electricity from lightning, and very slowly fading. After some days would become a domino effect. The shape copy the direction of the electromagnetic lines of force, that were created by the lightning, like a wire. Scientifically, experimentally verifiable. Unifying theory - explains simultaneously without any exception, all the so-called anomalies, such as geomagnetic variations, dead insects, dead and burnt plants, variations in growth. Crop circles are in fact made up in an outrageously simple, ridiculously primitive way. Never any supernatural powers, miracles, signs, space aliens. Very interesting, but purely natural phenomenon. Scientifically explainable, using only natural forces and principles.
