They’ve been throwing this phenomenom back and forth between real and fraud from since when they started. A lot of groups have stood forward and claimed it was them, even put up pretty good evidence for it: Made them infront of the eyes of the experts. Not that persuaded those who believe it is, and want it to be, aliens.
It’s like that with all phenomenoms. Two sides, and both as studdborn.
Maybe the crop circle spells “WHERES MY BEER WOMAN?” in alien language…
