Query: Crop Circle Hoax

The VERY FIRST crop circles were made by pranksters with ropes and boards. They have video taped footage of themselves doing it. Did the aliens then pick up on and improve on this method of "communicating" with pretty circles, or is it all just a big hoax that certain conspiracy addicts refuse to see?Open your eyes. It's a joke.
