re: Sorry Donald, but.........
Not to be disrepectful, you have many of your facts wrong.
There are plenty of instances of witnesses who see crop circles being made in "seconds."
Secondly, your all encompassing
>"There is not a single crop circle ever found that could not have been made by a human being." is a falsehood. I like how you think you are an "authority" here, because I doubt you have investigated them in depth as I have, nor have you worked with any of the scientists investigating this field.
However, I DO understand how as a math major, you are so convinced you have all the answers. I'll continue this later when I have more time.
