You're building a straw man, I haven't said that in any my posts. It wouldn't simply make any sense.
No we don't.
The standard model (of physics) does not explain gravity, as it doesn't explain the alleged dark matter and energy, the asymetry of matter and anti-matter and a couple more.
So are those supernatural? There must be some kind of double standard by which strong scientific evidence for telepathy in animals and humans is still labeled as "supernatural" while postulated "vibrating strings of energy", "branes" and "multiverses" are sound scientific hypothesis.
You're preaching to choir, mate

I am haven't said that. Again let's not turn this into a cartoonish caricature.
What I've said is that there are well documented cases of demonic possession that can't be easily explained away. Using scorn, derision and condescension won't make them go away either.
My only point is we know much less than we think we know, especially about consciousness. Only using an open and critical mind we can tackle these topics. Today's science is a powerful tool of inquiry when it's not restricted in small philosophical corners.
If one approaches the subject with any kind of prejudice, be it based on dogmatic religion, or dogmatic scientism, it's unlikely we'll ever get closer to the truth.
