Ho ho ho, get your tin foil hats out, folks. More seriously, I'd like to treat this as a conceptual exercise, so let's leave rationalistion and preceptions at the door, if we may, and simply play with a hypothetical... I've noticed a trend in various religious traditions, that effectively has a superior form of being helping out humanity in its formative period - a type of being that can be viewed as being spiritually intercessionary between Man and God. Let's take one: In the Bible, we apparently have angels walking amongst humanity - and blasphemies of blasphemies, some interbreeding occurs, and this is so damning that the progency - the Nephilim - are banished to a remote place on earth ready to await judgement in the End Times. If we look at this story with a modern (and unrestrained) look, it would be easy to interpret some part of this story as being some form of advanced alien race coming down among humanity, helping it develop, and then being punished for not respecting the bounds between the two. Now, call this a little insane, but every now and then, I seem to see this same motif appear in various other disconnected cultures, whether as plural (Nephilim) or singular (Prometheus). Sure, in anthropoloigical terms, I'm sure there's a perfectly reasonable concept reason for rationalising the view of intercessionary beings as a form of metaphor. But...somehow I have problems ascribing possibly shared human experience as entirely metaphor - after all, from a geological perspective, shared experiences of a "Great Flood" don't have to be the same flood - ie, a global event - but instead shared similar experiences of dramatic localised flooding. A literal seed for a greater mythology. There's something about the whole concept of intercessionary beings (call them gods, Angels, whatever) having shaped humanity that I find inherently compelling - as something to explore, rather than feel a need to believe in.. No, I'm not invoking a New Age language of Atlanteans or other speculative details - I'm simply talking about conceptual possibilities, that don't necessarily infer probability. I'm thinking in terms of some form of advanced race helping shepherd an extremely young human race, equipping it in certain forms, before eventually leaving to allow us to find our own way. As a hypothetical, is there really a suggestion of this in different cultural traditions? Or are there more compelling explanations?
