We should not expect it to be disordered any more than we should expect it to be ordered.

You can't just not have a prior. There is certainly no reason to assume the the universe as we have found has the default entropy. And we actually have tools that allow us to estimate this stuff- the complexity of the universe we find ourselves in is dependent on a very narrow range values in our physics. Yes I'm making the fine-tuning argument and of course knowing this stuff should increase our p estimate for theism. That doesn't mean P(Jehovah) is anything but minuscule-- the prior for an uncreated, omnipotent, omniscient and omni-benevolent God is too low for any of this to justify confident theism.
