flattop, I posted the website for the original crop circle makers earlier in this thread. They are artists (and human beings). www.circlemakers.org
This thread was reminding me of something that happened in the '60's when there were many UFO and alien sci fi movies and books that were popular, and lots of folks "seeing" flying saucers. I was wondering if these particular crop circles had been made by youngsters or adults. When I was a kid, the radio and newspaper in our town reported a landing of a UFO witnessed by boys near our town. There was a spot on the earth where there were depressions from the legs of the flying saucer, and the parents called the sheriff in, who was followed by reporters. One newscaster got down and smelled one of the dimples in the dirt where a UFO leg had pressed in. Yup, it sure smells different. (-- A cat had just previously peed in that spot). -- The boys finally had to 'fess up, espcially after the cat pee UFO odor was broadcast. They just couldn't hold their giggles any longer, but knew they were in big trouble. They had done the trick to tease a little sister, telling her the whole story of seeing the UFO, showing her the landing site. She ran to her parents, and it was awhile before the boys were able to back out of the sticky situation once all the grown ups became involved.
I had an art history professor who was very clear in his dismissal of the misguided who can't understand that humans in ancient times were capable of building very complex and awesome buildings and artifacts. The dedication that people have to a belief, and the lengths they will go to worship or appease their deity, is great enough to achieve grand constructions without any "alien" help. Just think of how many people went to their deaths in Aztec human sacrifices. The ability for humans to do things unthinkable for us or to build complex constructions existed long before our more developed technology.
