In the end, if you go all the way back through the chain of causation (whatever causation even looks like outside of the bounds of reality we know within our universe), whatever it is that resulted in our universe (whether it be the big bang or a god or alien that created the bing bang or a higher being that created said god or alien)…at some point, something must have come from nothing. It’s the only inevitable truth, and it drives me crazy too.

I don't see why it should feel bothersome.

To ask what came before the first moment is to apply a concept, time, where it no longer applies.

Similarly, suppose you knew everything. No matter what it was, how much information it was, you'd still be able to ask, "What's beyond that?" But being able to form those words doesn't imply the question means anything.

Isn't this only true if there is no physical infinity? I know it's-turtles-all-the-way-down is impossible for our brains to comprehend, but causality breaks down when infinities are involved. Another thing is that if space-and-time itself was born at some point (as they say), then talking about "before" and causality doesn't make any sense either.

But yeah, to your point, thinking that there was never "nothing", and that there always was "something" is equally mindblowing.

Unless the universe always existed. Why should there be nothing and not something?

And don't say "entropy". For all we know, the big bang occurred after a previous heat death.
