The Bible is NOT a history textbook. It is a book that conveys religious truth. When reading the Bible, we need to take into account that it's collection of books are like a library - we cannot read each and every book in the same manner. For example, we would not read "The Adventures of Tom Sawyer" with the same attitude that we would read "A History of WWII". Same goes for the Bible. The majority of people's questions about the Bible would be resolved if people would take this thought into account upon their theological study.
The Bible did not just fall down from heaven already printed. It IS God's word, but God did not simply tell the authors what to write, who in turn copied it down on paper. God left the authors the free will to write His Word with elements pertaining to their own time period. So, of course, things that make sense to someone living in 3000 B.C. would not be logical when read by someone living in 2000 A.D. It is still God's Word, however. People just need to take into account that the Bible's scientific and historical elements were based on the knowledge from THAT time period - not ours! Therefore, we cannot assume the scientific and historical elements to be necessarily true!
For example, let's take the ages of some of the famous Old Testament figures. The Bible states that some of these people lived to be several hundred years old! However, we know that this is not possible. This misunderstanding most likely came from a gap in the calendar system between our times and theirs. We follow the Gregorian Calendar, which is a revised version of the Julian Calendar. The inventors of both of these calendars lived long after the Old Testament was written. Therefore, we KNOW that the calendar system used during the Old Testament wasn't the same as today. Thus, with the application of a little logic and reason, we know that the age of Old Testament figures was not actually several hundred years old on the scale of today's calendar system!
The Bible conveys religious truth. Not historical and/or scientific fact. If the Bible was meant for science and history, we'd use it in school classrooms!
Scientific evolutionism CAN coexist with theistic creationism. As long as God put the whole thing in motion (but allowed things to evolve from there), there would be no conflict between science and theology. Even the Big Bang Theory can make sense in the picture! Did you know that the Big Bang Theory was hypothesized by an ordained Christian minister?

Natural selection is like this:
Say you had 10,000 mosquitoes put into a room. Then you spray pesticide to kill them. However, out of the original 10,000, 200 of them survive. They survive because they have a gene defect that makes them immune to the pesticide used. Because these 200 are the only ones left, they will reproduce and repopulate the room with more mosquitoes. Each and every one of these mosquitoes will have the same special gene that makes them immune to the pesticide, since they inherited it from their parents, who passed on the gene. This means that if the pesticide was sprayed again, all the remaining mosquitoes and their offspring would be immune. This makes the species stronger, and more immune to environmental factors that would have otherwise killed them all.
That's where the saying "survival of the fittest" comes from. Only the organisms that are equipped to survive the best will survive. The weaker organisms will die off from various environmental factors. This makes the species as a whole stronger and more durable. That is what it means for a species to evolve.
Natural selection is not really something you can argue about. It's just something that HAPPENS, regardless of whether you want it to or not. Ignoring this fact is pure ignorance on your part.
Besides, how is acceptance of this an automatic conflict with belief in God? I'm Christian, but I am not blinded by my belief in God so much that I stubbornly refuse to accept this fact of life.
