I could proclaim: It's just a theory that you exist.
Substitute theory for: The best possible explanation provided by the current accumulation of evidence.
Except that you can know for a fact a person exists as you can actually see them.

You misunderstand the Big Bang theory. It is totally agnostic (has no comment about) how the universe BEGAN. It is all about what happened starting at one Plank time AFTER the singularity (whatever that was) occurred. You can argue all you want about what the singularity is (which is what I think your arguemnt really is about) but arguing against the Big Bang theory is just foolish.
Not arguing against it at all, I'm just pointing out that no one can say with 100% certainty that that is how things occurred. All the evidence we have points in that direction. But just because there aren't any logical alternatives doesn't mean an alternative doesn't exist, as not all of the universe functions according to logic. Look at the laws of physics. Some of it flat-out doesn't make sense and is almost mystical, and very illogical, but yet it is reality. There could be an alternative explanation regarding the universe that we can't even comprehend with our current brains.
Sure, based on what we know and can observe, the Big Bang makes great sense, but what if there are aspects about the universe that we cannot observe yet, that we cannot even comprehend, that change things around? It's like trying to visualize more than three dimensions. Just because the brain can't do it doesn't mean they don't exist.
I am not at all dismissing the Big Bang, but I think when talking about the state of the universe 13+ billion Earth years ago, that there's the slight chance we could be wrong about something. From what I understand, no astronomer or physicist claims the Big Bang theory is 100% accurate, just that it is the most accurate theory we have right now. The original Big Bang theory had some problems. One theory that was devised that seems to solve a lot of these problems is inflation. Andrei Linde, one of the experts on inflation, said about it, "Inflation hasn't won the race, but so far it's the only horse."
Your misconception about what "Big Bang" means is VERY widespread, since it certainly SOUNDS like it means an explosion that started everthing.
That's not a misconception I have, although I can see that I gave that impression from what I wrote. By "beginning of the universe," I meant the belief that the universe was very compressed in the past and then expanded outwards very quickly. But I am aware that the Big Bang doesn't deal with the beginning (as in the literal creation) of the universe itself.
