I'm pretty sure the 1st law of thermodynamics states that in a closed system, i.e. the universe, the total energy is equal to zero.The energy would have to be constant if our system is an isolated system. (http://en.wikipedia.org/wiki/First_law_o...modynamics ) The universe of the theoretical Big Bang has to be an isolated, closed system. The story of Creation says that the universe was not always closed--an outside source served as catalyst for all its energies, namely God. You need evidence that our system has always been closed, but that knowledge is unreachable. So I still don't know why God would use the Big Bang because there seems to be nothing more known about the Big Bang than about Creation. In the beginning there was a burst of energy from one place--what else do we know? Do you have any other arguments why a creator would use the Big Bang?
I see what you're saying. I couldn't ever tell you "why" a creator would use the Big Bang. All I can really tell you is if there was a Big Bang or not.
The Big Bang theory states that the singularity was very very hot. This was proposed prior to the Nobel-prize-winning discovery by radioastronomers Arno Penzias and Robert Wilson in 1965, who discovered Cosmic Microwave Background (CMB) radiation that is detectable everywhere you look into the universe. CMB radiation is thought to be the remnants of this intense heat from the singularity.
NASA gathered measurements of the CMB radiation with a space probe in 2006. Together with measurements from an observatory in Chile, they were able to draw a picture of the early universe (as the CMB radiation has been bouncing around space for the past 13.7 billion years).
If I'm not mistaken, these are the "seeds of matter" that would eventually become the galaxies we observe now.
Another piece of evidence is the fact that the universe is expanding. Needless to say, this suggests that it all expanded from one single point.
So basically, the Big Bang theory predicted something, and as far as I can tell, the observations fit the theory thus far. Predictive power is a very strong confirmation of something being possibly right.
