Dream on brother. Your impeccable "logic" will build bridges and buildings......But not all crop circles. You assert that people must be the most simple explanation. I don't buy this. Not yet by a long shot.

In the Disney movie Signs, the circle formation is found in the middle of a corn field. In reality, corn is not the best medium for crop formations and very few are found in corn fields. When the movie's producers came to England to consult with circle experts, they were told the circles were made in fields of corn. To a European, corn covers all the cereal cropswheat, barley, oat, and so on. To Americans, corn means only maize. Hence the error.
