There are so many reports regarding this type of phenomenon that no one really knew which one is legit. Crop Circles are intrinsic and very detailed patterns made on crops which are somehow seen as a mark left by an unknown flying object. These patterns are found all over the world and some are even similar in nature which sparks the stories that the same ship must have landed in these crops. Although these patterns are very detailed and abstract, they can be replicated by human hands.
