"A point of creation would be a place where science broke down. One would have to appeal to religion and the hand of God."Natural – matter, energy, laws of physics, space, time.
-Steven Hawking
Natural causes cannot ultimately cause natural processes (circulus in probando).
Why would something that is not bound space, time, matter, energy, or the natural laws of physics be supernatural? If it can be measured, observed, or verified. If it indeed exists, then the laws of physics that will have to change to accommodate it.
If you're trying to appeal to something that cannot be measured, verified, proved, observed, or in any way else make itself open to evidentiary inquiry, then that's called snake oil.
Hawking is an atheist by the way.
