Just another episode of "Digging up Ancient Aliens." This time, they’re talking about aliens and heavy metallurgy. Apparently, ancient theorists think aliens gave us weapons and techniques for metalwork. It starts with fire, then goes through copper and iron ages. Oh, and there’s something about katanas being super weapons, but who really knows? Joan D'Arc's sword gets a mention too—some say it was special, but it’s probably just a regular sword. Not much excitement, honestly. #Aliens #Metallurgy #JoanDArc #Katanas #AncientWeapons
