interesting, S8. Have a look at Australian Aboriginal cave drawings, with people depicted with halos around their heads, that some interpret as space helmets. Look at the wonderful practicallity of their "Dreaming". Where did they get that from? In over 40 years in remote WA locations I've seen strange lights, sometimes scary, but always explainable to light refraction (atmospheric) or something. Never saw a green person. Maybe its only select people that see them?
