The recurrent laryngeal nerve - which runs from the head to the voice box - goes all the way down into the chest, loops around a major artery, then goes all the way back up again. It goes right past the larynx on the way down. All a decent designer would have to do is loop it off at that point. What we're looking at is the legacy of history.

Religion is the root of quite a lot of evil.

The assignment of purpose to everything is called teleology. Children are native teleologists, and many never grow out of it.

It could be that at some earlier time, somewhere in the universe, a civilization evolved by probably some kind of Darwinian means to a very, very high level of technology- and designed a form of life that they seeded onto perhaps this planet. And I suppose it's possible that you might find evidence for that if you look at the details of biochemistry, molecular biology, you might find a signature of some sort of designer.

The fact that somebody does good doesn't make their beliefs true.

There is something so mysterious that it is almost like God. God is in the equations. God is in the fundamental constants. And that's fine. I mean, that's just redefinition of that which we find mysterious at the basis of the universe.

If complex organisms demand an explanation, so does a complex designer. And it's no solution to raise the theologian's plea that God (or the Intelligent Designer) is simply immune to the normal demands of scientific explanation. To do so would be to shoot yourself in the foot. You cannot have it both ways. Either ID belongs in the science classroom, in which case it must submit to the discipline required of a scientific hypothesis. Or it does not, in which case, get it out of the science classroom and send it back to church, where it belongs.
