Crop circle
Crop circles are an unexplained phenomenon that happens when farmers walk outside one day onto their field and discover giant patterns that have been formed in their crops. This upsets many farmers, not so much because of the mystery, but because much of their produce has been destroyed for that season.
So farmers are not as worried about aliens as they are about how they will turn a profit this coming harvest. We understand their struggle, it’s not easy growing food, let alone dealing with the supernatural. If you were thinking of going out one night and making a crop circle, consider the harm you might be causing a farmer and his family.
