How do we know there isn't just as much antimatter as matter in the universe? There's no way to tell from a distance. Maybe 99.9% of it annihilated at the big bang, but uneven distribution left clumps of different types. The clumps could be the size of everything we can see now. Maybe the big bang sent some matter one way and equal antimatter the other way, and the anti side is just too far to see? We don't know what big bangs do. We don't even know what's a good question about that.
