Petroglyphs are vastly becoming an open interpretation of human activity. The carvings across the planet are similar and appear in discreet phases of a cataclysmic manifestation in the sky, so drastic, that it affects everything we know today.

Could this have been the manifestation of the Aurora Borealis, or Northern Lights, or something more sinister? BuzWeaver digs into the history of the phenomenon in this edition of The Lost History Channel TKTC.
