gnu - G'wan! You've just gone irrational over your unrequited love for Sarah Palin and it's causing you to utter bizarre nonsequitors and abuse your goldfish. ;-)

Lizzie - I have no idea if there's any correlation between crop circles and alien visitors from outer space. I am convinced, however, that many crop circles have been caused by some sort of unknown agency....not by us humans, that is. As to what that agency is or might be....? I have no idea.

It might be a completely separate matter to that of alien craft visiting this planet.
