The idea that there is a beginning of the universe is insane because it would have to come from somewhere else but there is nowhere else because the universe is ... everywhere. So there's nowhere for it to "come from" in the first place.
So the idea of like, "oh, well where did it come from?" it can't "come from" anywhere because it's everywhere.
So all the things in the universe can't come from somewhere else because there IS nowhere else (is what I'm trying to say).
So the whole argument of like, "Where did the universe come from, and where did it begin" is meaningless.
Cause we can observe everything on the planet, but everything on the planet is just a subset of everything. But we don't see everything. So when scientists claim to know the beginning of the universe, it's impossible. Cause you can't know about every thing, every object, in an infinite universe, cause it's infinite. Even if you found 99% of it, there's always 1 more percent of it, cause it's infinite.
So, (sigh) the idea that you can find the beginning of the universe,-that's another thing—if there's nowhere for everything to come from, then it can't possibly have had a beginning because it has to have always been there. Cause everything in the universe all the objects, all the matter, that makes up the things that we observe has to have always been there because there's nowhere for it to have not been.
Uh, if that doesn't make sense, then the whole beginning of time thing, that's the other thing "Oh, what's the beginning of time?" There is no beginning of time because there's always that one second right before that. No matter what point you point at and say, "Oh, there's the beginning of time," there's always ... the moment right before that. So, the whole idea of like, "Oh, well there's gotta be a God because otherwise the universe wouldn't exist," Well that doesn't make any sense; the universe always existed because it's got nowhere to go. It can't not exist. Cause it exists. At least we think it does.
So I dunno. That's my rant about all these theological and scientific questions about the beginning of time. There isn't any. You're looking for something that's not there. Because it has to have always been here because there's nowhere for it to have come from.
All right, I'm done.
And the point I forgot to make (I was driving as I babbled this into my cheesy microphone) is this: Although everything we see seems to have a beginning, middle, and end, those things are just temporary arrangements of atoms that eventually decompose. But nothing (observable at least) is made or unmade. Atoms and parts (subsets of the set of all atoms and things) just temporarily arrange themselves and fall apart. But the universe is not an observable thing; it is not a subset of anything else, so it doesn't have a beginning or an end, since it can't fall apart (there's no way for it to become separated from itself, since it is everywhere).
Since we see everything begin and end around us, we think this attribute applies to the universe, but it doesn't.
So the "where did the universe come from" and "how did it begin" questions don't apply to the universe itself, although these questions apply to all the stuff IN the universe.
