This past weekend I saw a TV special on Crop Circles, a phenomenon I have been aware of for years but never gave much 'serious' thought to. The whole idea that aliens are trying to communicate with us through strangely compelling circular designs stamped into wheat fields in the dead of night, or that this is the navigational system of choice of a species with technology advanced enough to permit space travel magnitudes more impressive than anything we have thus far achieved, well it all seems a bit fringe-y. On the other hand, some of the 'work' that has been achieved in the wee hours of the night doesn't seem like it could have been successfully pulled off by a very small team of people, and a larger group would inevitably have someone talking. Maybe it's teenaged aliens just having a go with the puny humans. Opinions?
