Stephen Hawking's book does not state that he is an athesist, or that he does not believe in God. Instead he talks about the complexities on of the universe, and the theory of multiverses. If one choose to believe God created the universe, could not God also have created multiverses?

If you respect him so much, you should probably read the book for yourself, and not base your opinions on media reports who may be picking and choosing bits or soundbites without even reading it, to make it more salacious or opinion-worthy, and a chance to pontificate.
