Are they manifestations of human consciousness? Is there an esoteric code hidden in their patterns that comprises a message for mankind? Are we in danger, and are crop circles some kind of warning signal? Or are they all created by natural, earthly causes?magnetic fields, underground water, plasma vortices.
