Just musing on AB's pretty much text book example of circular reasoning. On the one hand he thinks that the appearance of "fine tuning" must be evidence for a god who did it (what are the chances otherwise eh?), but on the other he also needs an "us" to be the intended outcome all along to do the observing (otherwise a sentient but different species entirely could draw the same conclusion about its god). The conclusion is merely in other words a re-stating of the premise, so the argument provides no new information.
No doubt he'll tell us that this is just a "clever" response and that, even if his thinking isn't "watertight", in some unspoken way it's still better than white noise rather then epistemically worthless but once again he'd be wrong to do so.
