What if our stories of gods, goddesses, saviors, angels, devils, souls, little men and green men, are not just stories of things our ancestors couldn't explain... what if they were accounts of events that, once upon a time, happened to mankind?
Suppose I suggested that you, I, and everything that exists is, in fact, immortal. Ah, but I presume you think physically immortal, right? Well, maybe we are eternal, physically and otherwise. Likely, we'll never know, but let's apply the Socratic Method and see what kind of answers we can question.
The modern age, most of us, accept the existence (or possibility thereof) of alien life, ghosts, demons, and any number of supernatural, paranormal, divine, or strangeness in general. Are we just superstitious monkeys or what?
With any such phenomena, there seems to be a clear dichotomy of those who believe it true (or believe the possibility exists) and those who do not, including those who make it their work to debunk everything unusual.
