When I see the awesome stone works ancient people produce I think a crop circle is pretty simple really.
People are ingenious.
You can have any design you want produced in a crop circle.
Professional circle makers have the experience and can deliver in one night,
It has become quite a cottage industry.
I love seeing them, and I like the mystery.
I appreciate the art form.
I just would not look for the answer to all humanities problems in them.
We need to solve our own problems.
