Hey all.
I want to pose another question I got from a friend of mine some days ago.
He thinks that the teleological argument fails in presupposing that life is more special than say a stone. The existence of life is (roughly) the same as that of a stone, a planet or any other phenomenon in the universe. Why on this view think that design is necessary for life, if life is no more probable than the existence of anything else?

You don't need to assume that life is intrinsically worthwhile. All you need to confirm a teleological hypothesis in any domain is to have a hypothesis advocated independently of the confirmatory observation, and then to make that observation.
For example, say I get dealt two random cards in black jack, a 4 of hearts and a 10 of spades. Now, say after the dealing, a friend of mine tells me that he thinks someone intentionally stacked the deck so I would get the 4 and the 10--no reason, just his claim. In bayesian terms, yes, his hypothesis is confirmed by the evidence because the existence of a deck stacker makes my cards more likely than the chance hypothesis. The problem with the deck stacker hypothesis, however, is that the prior probability is low because it is ad hoc and unmotivated.
Let's change the scenario a little. Say that a friend of mine has all day been saying that the dealer loves it when people get 4's and 10's in any card games. This fact motivates the deck stacker hypothesis when I find that I do in fact have the 4's and 10's, and thus the deck stacker hypothesis becomes pretty probable.
Same with theism and the fine-tuning. Theists have been saying for ages that the universe exhibits signs of design for life. Now that scientists have discovered that life is extremely improbable, the "cosmic stack" hypothesis is not ad hoc and is strongly confirmed by the observation.
