lol. you show your ignorance. no one here thinks crop circles are made by extraterrestrials because we simply don't have any evidence for that. but we have evidence that crop circles are definitely not done with conventional technology, which, in this case, would imply a vast man-made conspiracy to hide advanced technology from the public, which also implies a possible connection with ET technology, and so on.. you must also consider: who the hell has knowledge of sacred geometry and other advanced metaphysical concepts that are depicted by 90% of all crop circles? did you know that some crop circles have meaning? it's not just abstract art. if you study sacred geometry you will know this.
