I'm only trying to get a feel of this 'outside the realm of science'. Is String Theory also outside the realm as we can really run experiments yet to verify?
String Theory was precisely the analogy I was goign to use. While it's given us some interesting maths, it isn't really subject to experimentation-for the time being, though, and this is another discussion, String Theory is subject to more than a little bit of doubt and reworking in the community at present. Likewise, though, if one theorizes an entity that brought all of existence, space/time into existence, a good place to start is that such a being is by definition outside of those things. As such, experimentation to determine said entity's existence is beyond the realm of science, for the time being.
I mean, I'm fairly certain that I could come up with math that "proves the existence of 'God'," and that I could come up with math that "disproves the existence of 'God'," if I were so inclined.
I also can come up with math that proves conclusively that when no one is looking at it, the moon does not exist....:lfao:
