WHo would have thought my PhD in quantum mechanics could have been useful to this debate? (It ain't useful to me in any other way, mind...)

Having had to study and interpret a lot of Einstein, perhaps I can help here with a middle ground?

Whilst Einstein never professed a belief in a personal god, he did feel that as you can express physics by mathematical solution, it cannot be just chaos that developed in such a manner.

He said "God doesn't play dice." By this, he expressed his concern over probability and chance at the quantum level, as the laws around classical Newtonian physics were so fixed and worked at every observable level.

Whilst I don't have the quote to hand, (somebody else might?) he did clarify his position regarding the God concept by saying that aethiesm is chaos and under that condition, no laws of physics would work. Therefore, there is an order to the universe as expressed in mathematical terms. If you want to call this god, you are most welcome.

Obviously, he had no time for the concept of supernatural beings that can break the laws of physics or that mankind had some special status other than being special to each other. (I suppose by that, he meant you can go to a human and say E=MC2 and hope to impress them, but you would be disappointed if you tried impressing a goldfish by stating it.)

Oh, guest from sanity... Nobody "makes" light, it is a quantum event which we loosely describe as a photon. If you really must use biblical quotes to prove the god concept, I personally prefer God is Love. At least that calls out to human interaction and interventionalism. And is as much bollocks as the light quote....
