To be honest, I don't really know what to think about young earth/old earth, six 24 hour day creation, and the like. I believe that God actively acted in creating the universe (not the Deist, He wound the clock and let it run) and reject atheistic neo-Darwinian evolution that makes random chance God. I'm OK saying that I don't know just how to fit Genesis and the observable cosmological data. Nowhere does it say that God has to explain it all to me, or that I would understand it if He did. It is enough for me to believe that God did it.
I have a level of distrust of what has been called syllogistic theology. Because the Bible says A and the Bible says B therefore we must believe C. That works nicely for rather limited and well defined problems, but the real world is much less closely defined and there may be many factors that we just don't know that could introduce factors that throw the careful logical deductions off. The more we deduce and extrapolate from what we know to figure out what we don't know, the easier for small errors or unexpected factors to throw off the result. If one set sail from New York harbor for Liverpool, England with a precise compass heading to follow that turned out to be 0.1 degree off, by the time you crossed the Atlantic, you would not find England. When we sent men to the moon, they left earth orbit on a precise heading, far more accurate than 0.1 degree, but they still needed midcourse correction. It's not that I don't trust the Bible, I don't trust my or anyone else's ability to extrapolate from what Scripture says to deduce what it must mean.
The most important things for us to learn from the Bible are clear. Not everything is that important to nail down.
