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.
