It doesn't even make sense to say "before the Big Bang," in the same way that it doesn't make sense to talk about what's north of the North Pole.

Actually, the North Pole analogy is a good one. What is the horizontal diameter of the Earth at the North Pole (assuming north is up)? It's 0, right? But that spot still exists, and the diameter gets bigger as you go south. Same way that space-time gets bigger as you get farther from the Big Bang.
