Some rubes claim to have made crop circles with boards and rope......... They did.
and you can look at the mounds of photographs of incredibly sophisticated "crop circles" from around the world and believe these two rubes did them.
Straw man fallacy (no pun intended). They may have started the craze, but then other pranksters "from around the world" played copycat when they saw how much of a fuss the circles generated.
It's interesting to note that the temporal and geographic pattern of the spread of the "circles" follows the pattern of the publicity given to them. For example, when local coverage in region X of country Y gives prominent attention to crop circles, then voila, there follow a number of local "sightings". And so on.
No, dude, YOU are the gullible one.
If you say so, Mr. It-Must-Be-Aliens.
Show me where I said it was "aliens". Show me your evidence that crop circle proliferation followed "publicity" (pretty interesting, since they've been around for many, many years......and have been concentrated in certain geographic areas, totally absent in others around the world). Also, show me how to make these designs with boards and ropes without breaking a single plant, all plants laying down perfectly aligned, highly complex images only visible from the air, leaving trace radiation, etc., etc. Let's not go into how these would be done all over the world by incredibly talented hoaxsters without ever being seen. Golly gee. We need to round 'em up and put them in Special Forces with those skills.
Try again, sparky.
