Folks, here is my view as an informed Christian and a scientist (physician actively involved in basic medical science, sorry not geology). I think God gave us a mind because he meant us to use it.
Science is a great use of that mind and I think we can find out a great deal about the natural world and should make it a priority. I personally am fascinated by many areas of science and read widely. That said, I have never seen anything that contradicts the Bible, just some narrow interpretations of the Bible.
For this and other reasons I (like many Christians) welcome science and scientific discoveries ... the God of the Bible must also be the inventor of the natural world and all its laws. What we learn may change how I interpret certain parts of the Bible that are hard to understand in the first place, it is true. But that is because I realize that the Bible was written so that sheepherders who had no concept of what a dinosaur was could understand the sequence of creation (for example), and also so that a sophisticated scientific culture could also see a general outline.
So if by using the faculties God has given us, we learn deeper details of creation (chemical composition of early atmosphere, etc), I do not have trouble understanding that God had a hand in them. However, even though God is a true scientist and a brilliant engineer, many Christians aren't. That is why the Bible is not a scientific treatise and was never meant to be one.
Treating it as such and pontificating about the apparent inaccuracy of certain details written so that ancient sheepherders would be comforted in knowing they had a God who loved them is missing the mark.
Confront the real issue, whatever faith it is you are going to examine. In Christianity it is this -- humanity has rejected God, but he loves us enough that he has come here, lived as one of us in the person of Christ, and has died as ransom for our sins (willful disobedience of God) so that "whoever believes in him shall not perish but have eternal life(John 3:16)."
His question is not -- how comfortable are you with the fact that Genesis does not mention [insert specific scientific detail] so that sheepherders would not be bewildered? Instead it is this: will you accept my gift of salvation and invite me into your life or will you reject me knowing that there is "no other name by which men may be saved?"
This is what makes Christianity a dangerous religion, as an atheist friend of mine warned me. I completely agree -- Christ makes tough claims and asks difficult questions. But give our God your intellectual honesty before you reject him, first knowing that Science cannot protect us from the ultimate (and inevitable) requirement that we answer his real question, either yes or no.
