A few points here, if I may
1. Chrys, to some people the seven day first week is extraordinarily important. They reason that if the Bible could not get the beginning right, why trust it for anything else; or, at the least, where does one begin trusting it?
2. spunky, creation and evolution do NOT agree on the order of occurance at all! Creation has fruiting plants before any animals, for instance. It has birds before land life. In fact, it has the sun and the moon after the appearance of land on earth! You can't get a lot more different!
3. the "Big Bang" was a derogatory term used for the idea that the universe had expanded. Properly, it should perhaps have been called the Big Expansion, for nothing went 'bang'! What is interesting, however, is that the concept of a big expansion is exactly what the Bible presents. Twelve times God states that He stretched out the heavens. Ten of those times are in the past completed tense. It happened and was finished; it is not still expanding.
4. Nick, there is more physics in Genesis 1 than you might suppose!
In the beginning -- time
God created -- 'bara' something from nothing
the heavens -- space
and the earth. -- matter
We live in a time/space/mass continuum. This is basic physics!
In Genesis 1:2, we learn that the earth had a cold start, not a hot one, for "the Spirit of God was hovering over the waters." Not the clouds, not the vapors, but the liquid waters.
Physics.
"Let there be light" is the beginning of atomic processes. Physics.
5. IAMFREE (love your handle there!), the statements that God stretched the heavens are not in Genesis, but primarily in Job, Psalms, and Isaiah. For instance,
It is I who made the earth
and created mankind upon it.
My own hands stretched out the heavens;
I marshaled their starry hosts.
Isaiah 45:12
and eleven other places.
Also, the light was not the sun. But nor was it God Himself. It was our own quasar in the center of the Milky Way galaxy. It is not there now, but 'burned out.' However, the further out we look into space -- which means the further back we look in time -- the brighter and brighter are those quasars in the middle of each galaxy, each associated with its own black hole. We have the black hole left, but the quasar died away about the fourth day of creation week. It was the directional light which, when the earth was set spinning, gave evening and morning, the first, second, and third days. By the fourth day, the sun was either created or lit, and it took over the job.
Hope that helps a bit.
