do you believe in crop circles

No. Without exception, they have been proved frauds. Only the National Enquirer crowd believes in them.

I believe they exist. But no they are man made.

of course i do!
I have helped make Several!

I know that crop rotation in the 14th century was considerably more widespread after John. Is that proof enough for you?

O course because I've seen them. Do I believe aliens made them. No unless it was mexicans.

I'm pretty sure they exist....
...and they are typically made by humans

I don’t believe they’re anything paranormal.

No
