Getting Biblical

Last night I got thinking about Adam and Eve. This is a classic Biblical account that almost everybody has been told for millennia now. The real questions is how "real" is it? One of the LDS Articles of Faith states that "We...believe the Bible to be the word of God, as far as it is translated correctly." That being said and with the caveat that I do indeed believe a lot of the Bible to have been translated correctly and I especially believe that the antediluvian account as told in the Book of Moses to be translated correctly, how much of it is an actual, literal honest-to-goodness history and how much is allegorical and/or a parable.
There are some aspects that I think are definitely accurate - i.e. there was a man named Adam and a woman named Eve (or whatever their names were in their language). The question is were they the progenitors of the entire human race or perhaps just a subset of them. Perhaps Adam was the first prophet and the house of Israel descended through him? Perhaps he was the paterfamilias of some of the major groups in the Middle East but not of groups here on the American continent. We know, and the Hebrew backs it up, that the Earth wasn't created in 7 24 hour days, but rather 7 periods of time. Likewise, I think it's highly unlikely that Adam lived for nearly a millennium. It's more likely that that was exaggerated for some point or another. Since the Biblical account of the creation and ancient Earth history was from Moses' time period perhaps there was a more definitive account of what exactly happened and the Israelites knew more about the time of Adam and this was meant as a type for their lives or somesuch. I'll probably revisit this more because it's such a vast topic, but does anyone else have any thoughts? Post a comment!
