Causes of Crop Circles : with out view point (most possible explanations)

Crop Circles and their Unknown Causes Since I saw the movie ?Signs? a few years ago, my interest for crop circles greatly increased. In the movie, aliens who used the formations as a map attacked the earth. The suspenseful story line made me think whether this theory could be true, and if we may one day be under attack as in the movie. When I approached my friends for their opinions, I was surprised to …

…be aliens writing nothing more than cheap graffiti, some mad professor testing a new devise from his shed, or just pranksters. The important thing is the reaction to the circles that has an effect on society. For instance, movies and shows on television have been created, as well as several websites dedicated to crop circles. Magazines and books have been written about the topic as well. This overwhelming response has made the formations highly significant.
