Paranormal Adept
Regarding the 'Biblical Barrier,' I'm not convinced it exists, at least in not such a widespread manner as envisioned. Basically a lot of us are saying that the fundamentalists are too fundamentalist to handle it and they're all completely bat-shit crazy for believing such nonsense in the first place and they would absolutely freak out if the aliens landed.
I listened to an interview not long ago of an obviously fundamentalist theologian. He was presented with the idea of 'What of we are not alone?' He pondered a moment and said, 'Well, that just means that we'll have to enlarge our horizons and understand we have more work to do, more souls to save.'
That's a very earth centric and supremacist statement ... and exactly the response I would have expected LOLOL.
The fundamentalist theologian answered within a biblical framework where the 'others' were created within the same time frame as humans.
Had the question been: 'What if we are not alone and these discovered entities came before us and may have played a part in defining us' ... the response would have been a lot less politically correct LOL and this is really where you can find a biblical barrier. Saving a predecessor that played a role in defining you is a bit pretentious
Last paradigms were about displacing the center of the physical world from the earth to the sun to the center of the galaxy and finally to the center of an expanding universe.
Handing over the source of our sentience from a godlike entity to a flesh and bone entity that had abilities in genetic manipulation may seem over the top... but tell that to the square corn.
