Yes.

Ultimately, it is extremely rare in nature for there to be just one of anything. Phenomena rarely occur alone. Why should this not extend to the very existence of Universes, independent Big Bangs? Maybe the Big Bang is some incredibly rare quantum fluctuation in the vacuum that occurs by odd chance once every “ten to the ten to the ten to the ten…” years. Some freakishly long length of time. But who cares? There’s no one around to count the empty years. But once in a very blue moon, in some random patch of the vast infinite, infinitely expanding space time, a Big Bang occurs. It has its course and eventually decays down to nothing, returning to the quantum foam from which it sprung. In time, everything decays down to photons, those photons are stretched beyond the cosmic horizon. A Big Bang happens, a Universe thrives, and it decays to nothing. Awhile later, another Big Bang, etc.

So while a Universe is a rare thing, it is not unique. But in turn, it does give a sense of meaning. Suddenly we are now a part of a grand infinity of time and space. The concept of the Wheel of Time is made literal! And that is the thing that whole religions are built on. There are ways to find meaning in an infinite circle.

Why does the number 42 exist? Answer this and you will answer your question. Related question: does 42 exist even if there is noone there multiplying 6 and 7?

I don’t think so. Things seem to be leaning more toward the “stuff spontaneously comes from nothing” end of the spectrum as far as I know. Pre-universe causality makes no sense if our understanding of the universe’s origin is true. I’m personally OK with accepting that things don’t necessarily happen for a reason.

I feel this is not possible from inside the box unless something outside provides us the information.

We got about 10 years left to do anything radical to save our planet before all chances of known sapience are gone. Sorry bud, we’re still arguing whether we should oppress minorities and trans people, we ain’t figuring shit out.

I do not think we will. You can philosophize about it though but a scientific answer is unlikely.
The reason I think this is that I subscribe to the theory that the universe is the result of a black hole in another parallel universe. Black hole forms, eats matter and spews it back into a newly formed parallel universe, hence all the matter being present without us being able to explain how it came about. We call it the Big Bang. Likewise, we create new parallel universes with our black holes, the cycle continues. Always found it a neat explanation for it al.
But will we know ‘why’ our universe was created? No, we would need to look beyond the veil and that means going through a black hole and I do not see that happening anytime soon.
Problem with this theory is of course that matter keeps being flung around, what it the point of origin and will that deplete or be recycled?

Fascinating stuff and this theory I talk about is most probably wrong as I also believe we are not capable of handling this query.

We’re quarks on an atom, caught in an explosion, wondering why we can’t see past when the fire started.

I don’t think we will.

But religions don’t offer a good answer, either. At least those that a know. “In the beginning was god” But why was there god? What was there before god? What created god? Ask that in church and you get stoned to death. Or kicked out. Either one of that.

We exist to maximize profits for shareholders. I thought your boss would have told you that.

If there was nothing there also wouldn’t be anyone asking “why is there something rather than nothing”. It’s the kind of question that can only be asked in a universe that exists. Then answer to “why?” would basically be that because an unlikely even occured. It could just as well have not, but it did and now you’re here.

How does the positrack rear end on a Plymouth work? Nobody knows, son.

So, in the beginning, there were no “boundaries” because that would imply something exist.

So if theres no boundaries, it means the “nothingness” is infinite.

So somewhere within this infinity, there would be a random event which causes the matter and antimatter to not cancel out completely.

Edit: Non scientific, but, questioning existence is more of a philosophical question. Science probably would never answer it.

Why?
No
How?
Maybe

Science doesn’t answer the Why?* questions. Philosophy does.

Are we a brain in a jar living in a simulation? Are we creation of God? There isn’t an experiment that can test those hypothesizes.

* Why? has different meanings and science does answer some of them and the one that I assume you are asking is one of them that it doesn’t.

Solved problem. It’s 42. Next.
