Several years back around the time this was produced they had several old farts come forward and admit to being the creators of most of the crop circles (implying the other were inspired by copycats) I didn’t think much about it until they filmed them making identical crop circles using a board with a rope attracted at each end to trample down the wheat. And when I say exactly, it was absolutely the same as ones that had been seen showing up before. It’s certainly a very interesting thought, but this revaluation combined with the question why interstellar beings would be making arts and crafts in our farm fields completely wrapped up the phenomenon for me as a 100% hoax. Do I think we have off world vehicles visiting our planet on a daily basis, absolutely, but their involvement in crop circles? Absolutely not. JMHO.
