Why must a crop formation be symmetrical in order for it to be authentic?

If infact these crop formations are made by aliens, does that mean they are not allowed to make non-symmetrical crop formations?

Don't know. It's their rule, I'm just making them stick to it. Because the long thin one in the famous 2fer (the one next to the mars face looking one pictured on this thread a couple of times) can be "decoded" using "sacred geometry" many insist it's authentic. But of course it's not symmetrical which is a major portion of the "humans are too stupid to do this" portion of their arguement. IMHO, since the only useful evidence says they're all made by people the symmetrical arguement is BS. But if you run under the assumption that even though mankind can make 767s which have litterally hundreds of thousands of parts (and are symmetrical) we're two damn dumb to make a good look crop circle then symmetry becomes a "valid" judgement criterion.
