It’s possible that there is a god or something similar, but it’s not possible, as you say, to test it (at least not in the foreseeable future) in a meaningful way. We just don’t know, and have no way or knowing. Anyone can float a view from dreaming gods, through gnostic concepts, to simulated reality, and we have no evidence for or against and no real hope of finding such evidence.
