If we admit "god" and "nature" as "the way things work", it's OK for me. It's just names for the way of working of the things.
Where you are wrong, Tom, is saying that this name is the equivalent to the christian God, an entity with thought, intentions and plans, that's not what nature/god in your argument is understood, only the inherent characteristics of the things.
There are two different meanings, and you want to make 'em equal, and that's not possible.
@Cassiterides: Say again, where does God come from? And if you say "it always existed", I tell you "universe always existed", so... Where?
