Yep. But sadly maybe these "beings" if indeed it is alien entities that are creating these crop circles, are more intelligent then we are. Maybe, we were once at an education level where we understood and were taught advanced geometry, mathmatics etc. And it was common knowledge for the human being. Now, we have no idea what they mean, simply because we have been stripped of this privilege.

I still think we should be like the Vulcan's, teaching our young from adolescence of physics, science, advanced...Well everything. Just think, if we did that, by the time our children would hit adult hood they would be geniuses. And it would not be just one out of a million, it would be every human being on the planet. But look at what we have become.
