Origin stories are hard, if not impossible, to answer. Sure, we have the Big Bang. I've read the thing that exploded was estimated to be the size of a grapefruit. So where did the magic exploding grapefruit come from? The Big Bang pushes the quest back 13 billion years, but still doesn't answer it.

Or perhaps you like the theory that we're living in a simulation? I'd argue that is 95% identical to religion.

When I see this level of vehemence, I sincerely wonder if someone isn't concerned about the possibility of having to ultimately answer to someone or something for their life's actions.
