personally I believe when it comes to things like the possible existence of god-like entity and afterlives or anything that ascends the confines of nature and physics, human beings simply don't have the faculties to comprehend such things. I always liked the idea that our universe is just one of infinite and universes just pop into existence cuz fuck, why not. It's still funny to think though, that laws of physics had to exist before the big bang for such event to occur.
