I like the generalization that people say that you can't believe in the big bang and be a christian. I also like the generalization that you can't believe in Science relating to the Creation and be a Christian.
I have no idea how the universe was created, and there's no concrete proof to it either. Many people don't realize it, but from a historical standpoint, the Bible itself, in the old testament was oral tradition for many years until the Babylonian Invasion, and following Dispersion.....in which Jewish families were split off to different parts of Babylon to try and integrate the babylonian culture/beliefs into the Jewish way of life. It's at that time that most believe the Priests of the time began writing down what would later become the bible--well, old testament, as they saw their "oral tradition" failing....or fading is a better word.
That being said...without giving you a course in Religion History......Jews of the time saw God in tehir lives by the past (that's true even today)---by what he'd done for them. History was very important to them, as they saw how He delivered them time and again. Many theologians acknowledge that the creation stories (gen ch.1 and ch. 2) and the Garden of Eden are perhaps more true in their symbolism, then their reality. I get in this argument with Christians all the time....and they like to tell me I'm wrong, and sinning by disrespecting the Bible. But that fact remains....there is a chance that the Creation story is symbolic in nature....and that the story, when passed down orally before it was written---the mere purpose of it was to show God's hand in their lives, and their creation. Instead, somehow over the years, it's become viewed as more literal, then symbolic. Yet, for those who've studied Religion.....you do have to wonder why Genesis 1, and Genesis 2 tell two different stories of creation. If you don't believe me, go read it.
So to digress.....I still have a tough time believing that we came from Plankton---but I personally have no problem integrating Creationism with Evolution. Hard to argue with Fossils of early man. THe only thing I do believe is that God did create the Earth....and possibly that could be the Big Bang----So, in effect, both Creationists, and Big Bangers (wow, that sounds like a porn movie) could be right.
Either way, none of it can be Proven---so it doesn't matter to me. We're here.....
