To me it just doesn't make sense. I haven't seen convincing arguments or evidence that the universe could exist as is without god(s). Does anyone have such arguments and evidence that you can share?
I think that your problem is that you are stuck in a paradigm that you cannot justify without a belief in the supernatural.
But I would posit that an explanation is not a justification of belief in this case. Just because no one knows why the Universe exists in the way it does does not mean that supernaturalism is the answer. Least of all our intuition should be trusted when it comes to this matter as it's been shown that it's really unreliable when it comes to explaining the physical, same as our perception and memory isn't accurate at recalling or seeing physical events in many types of cases.
What about the Universe necessitates supernatural entities and why is that explanation intellectually favorable over an unknown naturalistic explanation? There are many things we know with upmost confidence that we did not centuries ago. Why should we suppose that the fundamental nature and explanation of the Universe will likewise hide in the god of the gaps?
Gods, deities, higher beings, really anything worthy of the title.
That doesn't really define what those things are then. "Higher" in what sense? How do we determine was is worthy of a title and does that mean that supernaturalism is not a required prerequisite? And if it's not how can we talk about the Universe existing without them, since I think it is quite easy for things to exist without titled concepts that humans, emergent only a few million years ago, conjured up.
Are you saying that "inches" dont describe any real amount of space?
I think their point was that inches by itself is a concept and that they don't describe any objective quality of space. Inches are based on a standard and there isn't any set "true inch". My search engine skills are a little lacking but I do recall that there is a specific object/ruler that the US government keeps at a constant temperature as the standard for what an inch is. Ultimately an inch is arbitrary which is why it isn't objective. It doesn't "exist" it's just a quality we made up for the sake of convenience. It's a mental tool. Gods could be considered real/unreal in the same way. That's the position I take but the difference is I'm willing to recognize that gods have nothing to do with the casual nature of the physical aspect of the universe and more to do with our minds.
Some of the arguments and evidence I've seen.
Again you avoid giving anyone a real explanation and instead shift the burden of proof onto someone else. Belief needs to be justified, not disbelief.
