Cosmologically speaking, here are the facts that we know for certain: the earth exists in a galaxy, there are millions of other galaxies out in interstellar space, all other galaxies are moving away from us (and we are moving away from other galaxies), the universe is expanding, the furthest galaxies are approximately 14 billion lightyears away from us and are at the edge of the expanding universe as we see it.
Now, if all of these things are moving away at a constant rate (meaning consistent, not necessarily the same speed), then it can be reversed that approximately 13.6 billion years ago, all of these galaxies were very close together and were driven apart by some force (possibly a "big bang" or sorts).
Now, it could be that God created the earth in 6 days and created it so that it looks like a big bang caused all of these galaxies to spread throughout interstellar space-time. Or it could be that God was the cause of this initial bang that seperated all of these galaxies and caused the universe to expand (string theory and membrane theories are speculative, because scientists do not know exactly what caused the universe to begin expanding or "bang", if you will.).
The only problem with the latter of these is that it "goes against" what the bible says. Actually, it goes against a literalist interpretation of the Genesis account. Understand, the Bible is written by people of Jewish descent. A common form of explanation of history or things that were not completely known is storytelling or mythology. I would suggest that the Genesis account is not a step-by-step guide to how God created the universe but rather a mytho-poetic explanation for what God did. This would mean that God did create the Earth, but did not necessarily do it in 6 days (also days are a completely relative term because time is relative and the Hebrew is ambiguous as to what is meant by "day"). This would also mean that stories like the Tower of Babel were not historical events perhaps, but rather explanation for why there are many languages.
I am a Christian. I love reading the Bible and I have grown to appreciate it even more when I was able to accept the fact that it has logical loophole and flaws. Those don't make it any less authoritative or important, it just means that Jewish theology revolves around block logic, so the scriptures are intended to be read as such rather than as a black-and-white newspaper. When you read the Bible with a western mindset, you are approaching it with an enormous bias that will likely skew the information that you take in.
