Why was big bang not a black hole?

The one thing about the big bang that has always confused me is why was it not originally a black hole?

Is this because a black hole has to exist inside an existing space?

Is it just true?  And we are still in it?

Or do we fudge the issue with inflation?  to get outside the barrier?

Or is a Universe by definition a black hole, there being no outside?

So the secondary questions are going to be something like

- can you have a black hole inside a black hole?

where do I find some thinking on this?
