Okay, here’s a paraphrased version that you might find more accessible, but before I render it, an explanation:
- The phrase “the supposed experience” means “the experience we assume to have happened” - there’s no point in debating whether it did or did not; we assume that it did, and that it meets the requirements of being convincing.
Mostly, the answers would be eminently shareable because they would pertain to a previously ill-defined aspect of the universe, ...
Yes, the answers would be shareable, rather than personal, because they would shed light on generally observable things that have so far remained unclear.
... and every more-or-less normal person experiences some parts of the universe in similar ways (though we may differ on the interpretations thereof).
Most people, i.e. those without gross brain damage or bodily deficiencies, experience reality in similar ways, but they may disagree on the explanation of those experiences.
But we need to be careful here also: if the supposed experience was limited to me, and only me, I'm enough of a realist to understand that it would be far more difficult to convince myself and others of its factuality; alternatively, if there was some way to record or retain physical evidence, and/or a very large number of witnesses was present who all told essentially the same story, my experience would then be much more compelling and plausible not only to myself, but also to others.
All this says is that one must also consider the [i]quality[/i] of the evidence, not only what it suggests.
In other words, if the supposed experience was sufficient [i]uneqivocally and objectively[/i] to transport a deity from the realm of conjecture and supposition, where they currently live, to the realm of observed fact, the consequences would be far greater than just the revision of [i]my[/i] beliefs.
The experience must be such that there can be only very little doubt about the actual existence of a god or deity. If it is so, then it would affect much more than just my beliefs - given sufficient time to spread, it would radically change the world itself, and the way people and I myself view it.
I hope that’s a bit clearer.
If you’re actually asking what type of experience I think I require to revise my views, that was not clear from what you wrote, and it’s a bit difficult to answer with specifics. If I was faced with an entity claiming to be a god, I would demand proof in the form of definite types and varieties of knowledge. For example, extensive knowledge of my past and current thoughts and actions; things currently beyond mankind’s grasp, such as a proof or counterexample of the Riemann Hypothesis, and a proof or disproof of the NP status of the general integer factorisation problem; clear resolutions to certain logical paradoxes and dilemmas; the ability to evoke particular experiences at will, and so on. I can’t readily think of a single experience that would immediately convince me. It would have to be a range of demonstrations of extraordinary powers. But such demands do not, of course, find favour with believers in a personal god, and, more importantly, I may still be dealing with a very advanced, but nonetheless mortal, entity, which is where the element of doubt would persist.
The only questions that would really haunt me afterwards is how and why and where the deity hid its presence so well for so long.
If, on the other hand, a theist’s god is meant, i.e. one who set things in motion at some point and then stopped caring about them or interfering with them, such a being is completely indistinguishable from what we call the “Laws of Nature,” and its existence or non-existence is therefore irrelevant - both to the universe and to me.
