A Deist would answer Hawking and say that God created the laws of physics.

God did not create the universe, says Hawking
By Michael Holden
LONDON (Reuters) – God did not create the universe and the "Big Bang" was an inevitable consequence of the laws of physics, the eminent British theoretical physicist Stephen Hawking argues in a new book.
In "The Grand Design," co-authored with U.S. physicist Leonard Mlodinow, Hawking says a new series of theories made a creator of the universe redundant, according to the Times newspaper which published extracts on Thursday.
"Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist," Hawking writes...
****Not only is there need for a creator of the laws of physics, there is the definite possibility that the laws of physics are not necessary. That is, other universes can exist in which the laws of physics are different. The astronomer Martin Rees has pointed out that half a dozen constants of physics don't have to have the numbers that they do. An infinity of other universes might exist in which the constants are different and,indeed, in which other physics laws are different. Not all would permit the development of the universe that we are familiar with and that Hawking is speaking about. This, in fact, answers the question that Deists have had difficulty with: "After creating the laws of Nature what HAS Nature's God been doing?" An answer is that He has been busy creating the laws of physics for the infinity of other universes.(How else to tax the infinite power of an omnipotent GOD? )****
