Personally, I think the Bible basically matches up to the Theory of Evolution. The order of things being created is identical in Genesis; with space, planets, etc. being created first. It then goes on to describe the establishment of an atmosphere and the creation of land and water. Even the creation of animals goes in order, starting out with small sea animals then large sea animals and then birds and then land mammals, etc. Everything was created before the development of mankind.
I heard an interesting argument on this the other day; I wish I would have wrote down the specific versus that they were talking about. I’ll give you a basic summary of what was said, and see if I can find the exact discussion later. The guy who was talking also spoke of how the Bible goes along with the events in the Theory of Evolution (other then the fact that people are the result of evolution, of course). He stated that the earth was created long before the story of creation found in Genesis; he talked about how the earth was originally the home to these creatures that were human-like but not human (i.e. that they were not made in God’s form so they could not communicate with him). Lucifer, before he was banished from Heaven, lived on earth with the people as a sort of pathway of communication between these “people” and God. As an argument for this theory, he quoted passages in the Bible that talked about civilizations being present on earth but no people.
And later (I think after Lucifer goes bad and is exiled) it talks about how God flipped the earth around and shut out the lights and destroyed all life on it (none of which is talked about during the story of Noah) he used this as proof that the earth was destroyed once before. And the fact that it talks about the earth being frozen in seconds matches up with the dinosaurs quick extinction. Plus, it also describes why human like skeletons have been discovered on earth.
Then he talks about the word usage in Genesis. How the word “let” has never once in any other form been used as a word for creation anywhere in the Bible, so it suggest that light and such was already present and was just shut off temporarily. So, the story of Genesis is a story of recreation and not the original creation.
I think a lot of his passages were from the book of Leviticus, but I’m not entirely sure. Anyways I thought he had some interesting arguments (although, I think they sounded better coming from him). Though, I don't know the exact context of his scripture quotes because I never looked them up myself.
There is not going to be some special key that reveals the truth in any case. But considering the date the Bible was written and how so many things match up with what is in the Bible and what is outlined in Evolutionary Theory, I think that creationism is at least in the running. I don’t think creationism could ever be proven, though, because all we have to go off of is “stories” and how those match up with the widely excepted facts.
