Just saw a special on Crop Circles, Have you ever seen any? What makes them?

For a long time i use to think that people did them but after seeing signs with Mel Gibson in it; i had to rethink what i first thought. First i thought it was just the croppers themselves going out at night and making pretty patterns in their crops. But later on it came to me some of the markings could not be made by a machine that was for cropping certain spaces between the designs. Now if it was a ship it had to be a nice size to make those pretty marks. Now the next thing that leaves that wide open is why at night. That part is where it make you think that it could be people being funny. But if it's not then that would mean we are not alone in this universe.

They are pretty interesting and I have seen so many shows on them but no one has been able to really say what they are or aren't. If they were done by humans they had to be very talented because they are pretty elaborate and often very large. Really makes one ponder if there is more the simple humans around this planet. Since it would take a pretty big team of people to make the crop circles and you know that someone would run their mouth about making it.
