Ever heard of Anthony Peratt and his career as a plasma physicist, who saw plasma discharge formations in petroglyphs from around the world? Pretty interesting and raises the question of whether some petroglyphs might not have been mythological, but recorded literal images seen by prehistoric people. That is, images of plasma discharge formations. There is a clear resemblance of these formations, from all over the world, in petroglyphs. Plasma discharges are electric and these same formations (like the "stickman" with a dot on each side of the waist) are still produced in plasma physics labs. But, when Anthony Peratt 1st saw the petroglyph pictures, those plasma discharge formations were still classified research. He is the namesake of the Peratt Instability, BTW, and worked at Los Alamos National Laboratory at the time. Just something to pique your interest. HTH and Thank You
