Kenneth Ring.....
Explored the realms of consciousness that these "alien" beings come from, deep within the subconscious. Or they could be using the subconscious to communicate with us directly, bypassing all our noraml filters. We see them as angelic or demonic, not much different from our ancestors who claimed god or the devil spoke to them, tricked them or showed them the light. If ufo activity increases as the years go by, and this communication increases (bypassing all our filters), maybe scribes will start rewriting the New and Improved Testament.
I can hardly wait.
