Here is a thought on crop circles you may not have considered, what if humans are responsible for making them, but the images are inspired by the Pineal Gland? Similar to the way auto writers claim they can create symbols or write for extraterrestrial intelligence .
Art and music and science have a quantum aspect to them which has been explained by some famous people when they refer to divine inspiration or say that the breakthrough for an invention came in a dream. For example, In biographies Einstein refers to a dream he had about cows jumping away from an electric fence as an inspiration for the theory of relativity.
Whether inspired or not, these crop circles are complex pieces of art certainly worth admiring, happy eclipse day steemit!

A worthy thought. Have you had the opportunity of visiting a crop circle? I did, in the 90's, it was in my home town. But the strangest (and coolest) fact was, the crop circle was The Flower of Life, this was a shape I doddled my entire childhood without realising what it meant... there are no coincidences. Have a great day. :-)
