Thanks, just glad people find it interesting. However I suggest you thank the guy who made this all happen to begin with, thousands, if not tens of thousands of petroglyphs and countless hours in the lab or sifting through images and stuff. I would really love to know how on Earth he even managed to link petroglyphs with plasma... Most people even now don't understand what plasma is (not the blood). And unless you happen to live around the poles or witness an extreme geomagnetic storm, you would never really see an aurora either.
