Indeed, just goes to show the ancient people of this planet knew more than we did but wrote it down as best they understood it which may have been lost in translation or meaning along the way. Serpents could easily be glowing plasma with discharges of electricity. This new information put along side the petroglyph stuff is really a mind blower. The ancient people somehow were able to see plasma and we cannot. Why is that? Is it because of the solar environment or because of something on Earth, perhaps even biologically, stopping us from seeing the invisible plasma around us.
