I never said that GOD is incapable of anything. I said as a human I see no way WE are capable of detecting the supernatural. We might believe we did but I see no way to verify or detect the supernatural.
Perhaps an actual unexplained event would make this clear.
In 1969 I bought my first car, I did a lot of driving and exploring of roads and places I had never been before. When coming back from visiting my cousin at Cornell a very strange thing happened to me near the town of Ovid, NY.
While driving I had a vision, don't know any other way to say this. Over reality I was driving my VW in a town I'd never seen, stores, cars parked along the street, and a green light at a major intersection. As I was driving through that intersection a white Ford Fairlane, speeding, ran the red light he had, so I was going to be t-boned. The vision ended.
This was so strange, I stopped the car and got out, to check and make sure I wasn't having some kind of physical or mental problem which would affect my ability to drive home. I could find nothing wrong, so just basically shook my head and returned to driving.
A little over an hour later I was driving into a town just north of Buffalo and suddenly realized this was the town I saw in the vision with all the same stores and cars parked along the road and the green light at the intersection. I slammed on the breaks and stopped just before getting into the intersection and a white Ford Fairlane blew through that intersection going about 50 right in front of me.
Had I not had that vision and stopped I would probably not be here today.
I have no explanation for this event, as my understanding of the world is things like this do not happen. However it did, so something is going on which I and other people don't know about. Still don't know what that is and in the following 44 years have never had anything like this happen to me again.
My wife of over 25 years never knew about this till a year or so ago when I told her about it. Her response as a devote Roman Catholic was "God gave you that vision to save your life".
Now as a deist, that never occurred to me, but if God does intervene I really don't know how he does it. I still don't think that is what happened but also I can't explain it. It doesn't bother me if my wife takes this as an example of her theistic beliefs being true.
Was this a supernatural event? Who knows, which I think illustrates your point which I quoted above.
Have a good one.
