These crop circles reminded me of Matthew 24:24 KJV-- For there shall arise false Christ, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Hoaxers admitted making some crop circles especially in England (accounts less than 2% of crop circles). The hoaxers' crop circles indeed showed that it's manmade (not sophisticated at all). On the other hand, UFOs (demons) crop circles, were intricate (showed plant stems with bent or blown nodes, showed plant stems with increased diameters due to intense heat applied during crop circle formation and the designs were mind bugling).
Several eyewitnesses say that bright, fluorescent balls of light hovered above the fields at the time the circles were formed. Because of these reports, Dr. Haselhoff researched these phenomena, and discovered that the plant stems inside these formations had increased in diameter, as an effect of intensive heating, with an astonishing circular symmetry. This effect perfectly matched the radiation pattern of an electromagnetic point source at a height of four meters and ten centimeters above that field. This is solid physical evidence that these eyewitnesses speak the truth. Dr. Haselhoff employed his analysis to other crop circles, investigated by others, and obtained identical results. However, the analysis failed dramatically on several man-made crop circles. He concluded that 'balls of light' must indeed be involved in the creation of crop circles.
