I
think space, as we understand it, has always been there.  Maybe not as
vast as it is now, but it has always been there.  Sometime, way back
when, there was a cataclysmic accident.  Several stars, or several
hundred stars were somehow drawn together creating the big bang.  I'm
no rocket scientist in any sense of the word.  I am just hazarding
guesses from what I know about space.
