Something that seems to plague conservative Christianity is the idea that the Bible is literally true, literally the word of god and that it is infallible. This becomes problematic from the very start of the bible with the Genesis creation myth. Besides the extremely basic distinctions between the "historical" texts, law texts, prophetic texts, gospels and epistles, biblical literalists don't seem to be able to grasp the more specific genres contained within certain books.
First off, with Genesis, the first few chapters belong to the genre of Creation myth. The Genesis story is not unique, original, or true in any sense and to interpret it as such shows an enormous misunderstanding of the genre. It isn't meant to be interpreted literally because creation myths were symbolic narratives that described how the known world came to be, not scientifically accurate accounts of actual events. They developed in the same way most folklore does, by being passed down orally through many generations. Genesis was written down to preserve the cultural tradition of the Israelite creation myth. This is most likely the reason why there are two different accounts of the same basic story contained in Genesis. Chapter one and two give two divergent accounts of the same basic story, the events are in different orders, one contains details that the other doesn't and vice versa. The biblical creation story is a myth, nothing more, and we find parallels to it all throughout early human history, many of which predate the Israelites. If you want to understand the Genesis creation narrative, you interpret it within its cultural context, not take it as infallible, literal truth.
