Ooh, so much to cover, so little space. XD
I ascribe to a not completely literal view of Genesis, and there are a few reasons for this, and I'll try to explain it as concisely as possible. The broadest reason I can give is that God (remember, Jesus IS God, they are one and the same) speaks in parables, stories that may or may not be true, but more importantly, illustrate a spiritual truth.
Genesis may be a parable. I am not denying it could be 100% completely accurate, because I do not know, I was not alive at Creation. What's MORE important than whether Genesis is 100% accurate or not is the spiritual truth that God created the universe out of nothingness, all by Himself, and why we live in a fallen world.
Remember, Genesis was written for Hebrew slaves freed from Egypt, not for scholars. If I wanted to explain to you guys how, say, a nuclear reactor works, I wouldn't give you a completely, 100% accurate account that went into detail, because you'd be absolutely lost. You haven't had the education to understand it. I would give you a simplified version, dumbed down so that it would be easier for you, who has not had that training, to understand it.
So it could be with Genesis. I think the biggest proof of this is Genesis 1:16, which I will quote from the NRSV:
"God made the two great lights--the greater light to rule the day and the lesser light to rule the night--and the stars."
As any astronomer will tell you, the moon is NOT a light. It reflects the light of the sun off of its surface, giving the ILLUSION that it is a light, but it is not. Would the Hebrew slaves have understood this concept? Probably not. All they understood was bricklaying and getting whipped. So to make it simpler, it was dumbed down so that there were "two lights," even though there is only one light in reality.
Again, I don't deny that Genesis could be 100% literal. I wasn't around when God created the universe, so I can't say for sure whether it took 7 days or 4 billion years.
Okay...done with that... *whew
Since the lack of complete free will (since if we had complete free will, we would be able to choose not to sin, but this is not possible) and Satan's existence as a real, living thing have been more or less covered, I think that'll about do it for me, huh?
Oh yes, and Romans 3:9-20 do a pretty good job of summing up that no one is considered righteous.
Okay, this was a long post, I'm outta here... >.>
