I also meant to add this. I think six days is more than enough time for God to do a perfect job in creating all of existance. I think he could have done it equally or better in six seconds. It seems more belittling to think that he needed thousands of years to do what he could do in an instant.
Also, all of this really depends on your world-view. What you believe seriously alters the way you perceive things. An Atheist scientist and someone with a Judeo-Christian world-view can determine wildly different things about our origins from the same evidence. It's all in how you look at it.
But something I have noticed is that big-bangers, evolutionists, and the like will find something new, and then find some new way to fit it into their beliefs, which is why the various dates keep changing (ie: the big bang, the extinction of the dinosaurs, the dawning of man, et cetera). They already believe in millions of years, so they think nothing of tacking a few more hundred million on there. They apply their conclusions to the evidence rather than using the evidence to reach a conclusion.
I can't say Christian science is totally innocent of pushing their world-view on their findings, but I can say that there hasn't been anything discovered that has caused us to have to rewrite the Bible.
