Part of the reason that some people don't take everything in the Bible as the literal truth is because of the language it was written in. The Bible is almost 2000 years old now, and language has developed rapidly since then. If you asked someone 50 years ago what an MP3 was, they'd have no clue. The same can be said of the language used in the Bible. It had to be written in a language that could be understood not only by those writing it, but also those reading it 2000 years later. It's also part of the reason that translation is so hard. As language evolved, there became new meanings for different words, and different meanings for the same word. It becomes complicated. This is probably my biggest beef with those who believe in a completely literal translation of the Bible... and carefully neglect the words "Judge not lest ye be judged". They use it to point fingers when the main goal of being a Christian is to 'love the sinner, hate the sin'.
Anyhew, yeah. That's why we can believe in both creation and evolution.
