It is possible that the Big Bang is the start of the time. But there is also another possibility: that the Big Bang was only a local phenomenon. In this case the universe would be something much much bigger and almost void. Maybe there are other regions with matter, but so far away that we cannot interact with them, and the light coming from them just dissipates on the way. Maybe there is a law of Nature, that if some very big region of the universe is too empty, there must occur there a local big bang creating some matter, such that a kind of equilibrium is recovered.
If we think on the way Physics developped since now, it was always like this: physical theories (like Galileo's mechanic, and so on) proved to be only local and partial good descriptions of reality. I do not see why the Big Bang Theory would not be also only a local approximation of the universe, which proves false if seen at a bigger scale.
