If the big bang created space and time, "before the big bang" is not really well-defined.

  Unless you believe that this universe is just playing out holographic on the event horizon of an N+1d black hole in our parent universe. The Big Bang was just the singularity birth of that one object.

    Except not all dimension numbers have nicely defined physics and geometries. For example, 4+0 and 4+1 don't have symmetric pairwise particle interactions in the sense we have in 3+1.

      It's going to get really irrational if we discover that the universe is only 2.71828... + 1 dimensions.

    From inside that universe there still was no "before". Are you looking into our universe from the outside? ;)
