Literal. If you don't take it as historical the rest of the Bible is pointless and mostly a lie.
Historic poetic. That it is different from any other historic section was reported by the committee on creation to the OPC. The evidence that it is poetic is rather overwhelming ... while I now have held a framework view for years, having read through the subject in detail recently has convinced me even more.
Age of the earth? Unknown. While it could be young, it has apparent age that it is very old. It makes absolutely no difference to the veracity of the Bible.
Literal Adam.
God created.
While I don't believe the creation account says anything about evolution, I don't think evolution is true for mathematical reasons (probabilities on the order of 1 in 10 to the 75th power are essentially zero, and beyond credible belief ... one would have to suspend any claim to rationality to believe evolution.)
As to what is figurative and what is literal, the things I think are purely literal are few ... literal Adam and Eve. Literal fall. Literal creation (meaning God did create). Literal snake.
The days I take as figurative as they appear to be from anything more than a cursory reading of the account.
What I find amazing is that while many attribute anything but a literal interpretation of 24x6 makes God to be a liar, they don't see the same problem with apparent age of the universe.
I also have a problem with some creation scientist knowingly and falsely pushing what they now is false in order to put up arguments for God (who doesn't need their help). There are many of these that are just poor science (Paluxy river, the NASA computer simulation hoax, etc.) which are either entirely baseless, or outright fabrication. These things hurt the cause of Christ in the world.
The real world and the Bible cannot have contradiction; if the real world contradicted the Bible, then general and special revelation contradict each other, and then God would be a liar. That is not true, so the premise is false (general and special revelation must therefore be in perfect harmony).
If we have a world which is less than 8000 years old, then it behooves Christians to understand and find out the explanation for the apparent age of things that seem much older, and to do so logically so there is no contradiction between general and special revelation. We are the ones with a world view that allows science in the first place. We are the ones that say God is not the author of chaos, but order. We are the ones that should make sense of what is revealed in both the natural world and the scripture without resorting to God being "the great deceiver" and making the real world a deception and full of lies.
Our God is truth itself. If we state evidence cannot lead to a particular conclusion because we see something else in scripture, we need to explain the evidence without saying "it has no basis in reality." We should be at the forefront of all the sciences, not on the sidelines taking potshots that don't hold water because it would cause us to change our interpretation of scripture. We need to lead the way, discover the things revealed. Not just by looking at the book of God's Word, but also by looking at the book of God's work.
