That documentary just blew this whole [cue the On Step Beyond music] "Alien Crop Circle" thinga-mahoozy right out of the water.
You're kidding, right? No one on a website full of intelligent people actually believes this, do they? Some form of alien intelligence visits earth and leaves no signs of their appearance other than smashing some unfortunate farmer's corn?
People use rope and simple surveying tools available for hundred years, they cause lots of damage to some guy's crops, and that's it. End of story.
If you honestly disagree, why don't you describe what the holes in the program were? What holes are there in:
1) Getting some guys to make a human-made crop circle
2) Bringing in the fake alien researchers and demonstrating that they know nothing by having them fail to analyze the crop circle
