Haven’t crop circles been repeatedly shown to be hoaxes?

Yes, some have been hoaxes by clever people. But if you look at several years worth of circles you’ll see lots of very intricate patterns that cannot be easily made. Such large and suddenly appearing designs are almost always geometrically perfect, which is not a hallmark of a couple of guys with paddles stomping around in the middle of the night.
I have no idea what’s behind this phenomena but its peculiar enough to warrant some scientific study IMHO. Bear in mind that while most circles appear in England, they have appeared elsewhere in the world.
The circles are well documented so you may want to examine them and reach your own opinions about their possible origin.
