The key is "depending on how you interpret Scripture". I don't have a problem with the age of the Earth being very, very old. I think that some of the accounts in Genensis happened far longer ago than the YEC say which could be why there has not been any evidence to support them found YET. The Bible doesn't give the specifics on HOW much of what it states happened but I don't find as much discrepancy as some here do.
I don't know a huge amount of ID theory, but from what I've gathered here, I don't see that ID denies the evolutionary process at all. What it seems to be saying to me is that everything was created and designed and evolution was the mechanism used by which life evolved on the Earth. I don't see that as a contradiction to evolution at all, unless evoluion can definitively state that there was no design or purpose.
Evolution doesn't have anything at all to say about purpose. As for design, that is what natural selection attempts to explain. No alternative mechanism has been proposed, at least according to Behe, testying in court under oath.
