Crop circles in Sandyville, Ohio! Real or fake? Alien life?

I don't know what to believe, but if they are the work of pranksters they did a darn good job! I saw actual pics of this from family members who live nearby, it is very uniform! I don't believe in ufo's etc, I guess because I have never seen any proof! What is a logical explanation? Just they work of some crafty teens?
