I'd just like to mention a few things here, even though I haven't read the entirety of this creation/evolution debate.
Firstly, as "symbolic" or "metaphorical" as you want the Bible to be, the 6 days of Genesis are still out of order with the way evolution says it happened. For example, the sun is created after the grass. So even if we view the days as "symbolic" they're still all out of order.
But there is another, more important point I'd like to make. Suppose you're a Christian who believes you can reconcile the six-day Genesis account with evolution. There is still a serious hurdle because of the Great Flood in the Bible. No matter what, as a Christian, you must admit to several possibilities:
1) The Great Flood of Noah happened as described and modern geology has misinterpreted much of the data. This would mean that many of the fossils that they're uncovering, which they believe are evidence for "evolution" did in fact die in the Great Flood.
2) You believe that the Great Flood was a "local" flood which essentially negates every description of Noah's Flood inside the Bible.
3) You believe that the Great Flood of Noah happened and left virtually no trace (impossible).
4) You believe that the Great Flood was a "parable" which also denies the words of Jesus Christ (Mt. 24, etc.) and Peter (2 Pet. 3). This interpretation is untenable.
The only possible conclusion that you, as a Christian, can come to is conclusion #1 - which still leaves you at odds with modern geology, even if you have managed to reconcile the theory of evolution with a "symbolic" six-day Genesis account.
Let me also say that there is a ton of evidence for the Flood that evolutionists seek to minimize and are quite prejudiced against. If you go to websites such as
www.answersingenesis.org and
www.trueorigin.org you will find many strong arguments for the Flood and for creationism from extremely intelligent, credentialed scientists.
As a Christian, I know that the Bible is true and the Flood of Noah really did happen. I also do not for a second believe in the theory of evolution, and think that the people who do believe in the theory of evolution are quite deceived and are in for quite a shock. However, that being said, believing in evolution does not affect salvation. There is a way you can know that the Bible is true, and not believe, or think, or "imagine" that it is:
"
16Jesus answered them, and said, My doctrine is not mine, but his that sent me.
17If any man will do his will, he shall know of the doctrine,
whether it be of God, or whether I speak of myself." Jn. 7:16-17
The entire NT has verses in it like this. You can know, and you can know for a fact, whether the Bible is true or whether it's a lie.
