^Supposedly, such a being would not be bound to the normal rules of the universe and thus does not have to be "created". At least that's what I would argue as Devil's Advocate.
But really, this is pretty ridiculous of Hawking. We don't know what happened before the Planck epoch other than that there was a singularity at some point. What came before this singularity, how it formed or who perhaps created it is not knowable with our current technology and methods, so how can Hawking really rule out that God did? Does he have concrete evidence that a supreme being could not have (theoretically)? This just defies logic to me.
Also, how can gravity create matter?
