Predict? I think your scope is too limited. So long as you can't control everything that happens you should realize there is more to know. However, when you gain complete mastery over your universe will you rest in knowledge complete without imagining other universes which may exist beyond your own physical realm?
I'll worry about those when there's evidence for them. In the mean time they're just fancies of the mind.
His science studies are entirely secular material.
I just make sure to tell him that God is the creator of what we're learning about.
And I'm telling you that whether that's true or not is inconsequential.
Iron:
The question is was everything created or not? If it was created then everything itself is evidence of a creator.
You're on a wild goose chase. You're asking if we'll ever find evidence of supernatural stuff while looking thru a natural, empirical lens.
You will never find any proof or disproof of something that's outside the scope of your inquiry. You'll never know enough to pretend to see God or his visions or whatever. You can have faith that you do, but you can't show any supporting evidence for it, and so, those effective fancies of the mind have no sovereignty anywhere outside of anyone's mind.
If I had any faith about anything, this last notion would warrant never admiting it, or doing anything that'd be justified only by that faith. Just like you can't kill people and then testify that God told you so, or (less polemic) that you had some divine inspiration that took over your conscience, you can't assert anything of faith as true, except in the sense that you believe in it.
