Here is a video I came across of recent crop circles formed over Great Britain that are very detailed and complex with references to Carl Sagan’s discovery of a code that NASA sent out in the mid 70′s.
Could someone have done this as a huge giant prank? I think that possibility always exists, however, with these new designs of the crop circles and the complexity of it, I am not sure if someone could do it in the middle of the night without using a large light source that would attract attention.
Many people say they experience a strange euphoric feeling when standing in Crop circles and that compasses act crazy. The video does not say anything about how people feel when standing in them, but if they really are created by extraterrestrials, then maybe the euphoric feeling and the strange phenomena are caused by high radiation left over from when the crop circles are created.
