My understanding is that the big bang wasn't matter expanding into space-time, but space-time itself expanding from a singularity. If this is the case, then asking what caused the singularity is problematic. The entire concept of "before", and by extension cause and effect relationships, are meaningless in the context of this singularity.

That is, the existance of the universe doesn't need a cause, and if it does, there's no way for us to know what that cause was.
