I had a shower thought the other day: clearly conservation of energy is just a guideline and not a fundamental law. Otherwise, how could anything exist?

Well... conservation of energy is just a law within our universe. Everything in here is energy, e=mc^2 and all that.

But the creation of our universe definitely involved some process that dumped a shit ton of energy into a very small space about 14 billion years ago.

Why does something exist? There is an easy answer: Because it can.

Similar to the many world interpretation of quantum mechanics. All possibilities exist. Both a something and a nothing.

Survivor bias. If nothing existed [1], we wouldn't be here to ask the question. It's like asking what is P(A|A). The question "Why do I not exist" has never and will never be (seriously) asked. [1] To be clear, if only nothing existed, and there existed nothing other than nothingness. [2] [2] I sense epistemologists warming their guns here, asking if the "existence" of "nothing" counts as the existence of "something"…

You say this like it's a solved issue, but you're still debating with yourself in the footnotes.

A former physics professor of mine said that energy was not in fact conserved in the Universe because the expansion of the Universe consumed the energy. The total available mass-energy in the Universe is decreasing over time.

I don't think so. There has to be a plausible survivor for survivorship bias. Living forever is advantageous to being a member of a survival cohort, and yet survivorship bias hasn't discovered any immortal people. Is there a plausible reason for things to exist that would explain why existence survived as an outcome?

Isn't it the opposite of what you suggest? If there was nothing, there would be nothing to investigate; but now that we now the universe exists, it does make sense to ask why is that something exists rather than nothing.
