Supernatural is that which we humans could never devise a scientific explanation for.
If I may, I'll pretend that I know where this is headed and jump to the final point.. I think we have our life here in the material world. I think we have brains to help us figure things out on our own, as far as we might. I think we may or may not have something supernatural waiting for us after we materialy die. I think if that's the case, we'll have eternity to figure out what happens after we die. I think it's a waste, of what we've been given, when time is ticking and our material choices decide what happens right now, to wax supernatural on our religious fate. I think we are here in this material world, left to do our best.
I think reason is our best material hope. I think any faith we have today in this material world will never compare with the Truth. I think it's in vain to try and pretend we know what we'll know in the infinite supernatural realm.
That's just my supposition on the supernatural. I don't think it trumps realistic, scientific reason at all. I believe what I see, not what I can imagine without practical confirmation.
