They're not "faked." They're just being made by humans. Nothing fake about them. The problem of "symmetry and precision" is bogus. I've already explained (post 462, 488, and 492), how a very intricate and precise crop circle can be made. With practice, it should be no problem at all. It only required minimal thought to devise the techniques I wrote about. If I really cared, I could do much better. As I said, this ain't rocket science.
Now then, we're left with the "mystery" of "bending the crop at 90 degree angles." Is that what only the aliens know how to do? That's it? You're hanging on by your fingernails. It must be painful.
Show me a documented "hoaxed" formation that displays the symmetry and precision of a REAL formation, then maybe I won't laugh so hard at your claims..
Incidently, how do YOU explain how one would bend ALL of the crops at 90 angles in making the formation without damaging or breaking them? And what about those weaving patterns?
