Of course not. And no one is suggesting that we should – except for the Intelligent Design people. That’s the problem with the idea of ID as a “scientific theory.”
People have this idea that Darwin wrote his book, and scientists everywhere just said, “OK, cool, let’s go with that.” They didn’t. They have performed more experiments to test the validity of Darwin’s ideas than have been performed in almost any other area of science; the result has been that we’ve found that Darwin was wrong about a lot of the details, but that an overarcing evolutionary process is indisputably shown to have happened by every empirical measure we’ve ever been able to find.
But here’s the key bit – they still haven’t stopped. To this day, we’re still examining the evidence, trying to find holes in the theory and see if they stand up to scrutiny, because that would mean we’re still not there yet and that the theory could still be more accurate.
Under the current system, if we can’t figure out how the eye formed, we spend decades – centuries, if necessary – trying our very best to work out exactly how the eye could possibly have happened. Hopefully, eventually, we work it out. If the answer turns out to be incompatible with evolutionary theory as we know it, we will amend the evolutionary theory. (So far, however, the eye doesn’t seem to fit that standard.)
Under ID theory, you just say, “See! The eye couldn’t have evolved! God must have done it!”, call it a day, and go on home.
If scientists ever do find hard evidence of a designed universe, believe me, they’ll trumpet it to the rafters. It’d be the greatest scientific discovery in the history of our species. The scientist who made that discovery would be remembered for as long as our civilization survives, if not longer. (Although I suspect that if such evidence is ever found, it’ll be found in the field of either astronomical or quantum physics – or string theory, maybe – rather than evolutionary biology.)
But so far, no one’s found that evidence. The problem with ID is that it pretends we have, in a very unscientific way.
