Are they made by extraterrestrials? Time travellers? Government researchers testing out secret technology?

Whatever they are, I find it hard to believe what the skeptics believe: that all crop formations are made by bunch of greasy, chubby college-dropoutsusing rope and wooden planks.

I have yet to see any skeptic offer proof for their claims. Until a video surfaces on Youtube showing a group of people making a 350-foot wide formation in PITCH BLACKNESS in the middle of a farm, WITHOUT GETTING CAUGHT, in LESS than 12 hours, then I will remain convinced that such a thing is simply not possible.
