Interesting thoughts to consider, Juan.
Losthobbit, I think you do yourself and others a disservice when you say that it must be taken literally. It is certainly your choice to do so, but it just isn't true. It is obvious that not everything is meant to be taken literally in the bible. Example - Christ is the light of the world. Is that supposed to be literal? Was he a walking glowstick? That is one of many such examples, but I used it in the hopes of pointing something out in your analysis that you might not have considered:
So God created the heavens, before he created light? Okay, I suppose this could be possible, depending how you interpret it, like "heavens" could refer to the atmosphere, but it sounds to me like he made all the stars, but they weren't glowing. Lets skip ahead to verse 14...
Gen 1:14 "And God said, "Let there be lights in the vault of the sky to separate the day from the night... etc."
Gen 1:16 "God made two great lights-the greater light to govern the day and the lesser light to govern the night. He also made the stars... etc."
Confusing ... I thought he already made the light, back in verse 3. Anyway, it sounds a bit like God is using a 3D modelling program, like 3DS max, where you can create things in any sort of order, and enable them, and then disable them.
It does depend on how you interpret heavens. Is it atmosphere? Outer space? Or heaven as in the spiritual realm?
If Christ is the light and life of the world, then I think the light that was created is Him. Then the lights in the vault of the sky are stars; and the two great lights are the moon and the sun. Literal, physical lights as opposed to the spiritual light and life of Christ.
Now as for the second story regarding Adam and Eve, I agree that everything in that story is representing something else. The tree of life symbolizes life. The tree of knowledge of good and evil symbolizes knowledge of good and evil. But people understand a lesson better when they can visualize it, so the things that were being symbolized were given something concrete for people to visualize.
