That's a flawed analogy. There is nothing to lose by believing in God. If by chance it's all false, then it does not matter what I believed in, whatever I'm destined to go when I die will happen. However, if God does exist and the Bible is true, then there is a lot to lose by not believing.
Believing in the big bang takes as much faith as God. The fact that nothing bumped into nothing and ended up creating life and a whole universe is quite far fetched when trying to think 100% scientifically. Matter can't be created from nothing, and even if it could, there would need to be some kind of force to initiate it, but if no matter exists to begin with, then where is this force even going to come from?
Either way, I could not care less what people chose to believe in, but it just pisses me off when people bash someone because they don't believe the same thing.
Only on the surface is believing in the Big Bang an act of faith. There's a difference though: shitloads of evidence in support of the big bang theory. In fact, MOST Christians in the world believe in the Big Bang Theory. Furthermore, define "nothing." If you take a cubic centimeter of "space," and create a perfect vacuum with "absolutely nothing" in it, then particles are going to pop into existence and out of existence continually in that space. Particles that did not exist. This is well known, and tested (and you can throw out a lot of your electronics if you don't believe this, else you can declare that those electrical engineers don't know what they're doing. My computer works on magic provided by God.)
Nonetheless, *I'm* not going to type out the evidence for the Big Bang here - even a summary would be as long as this thread (which makes your statement - it's a matter of faith - to be rather laughably incorrect.) Here; sorry about the particular website, but I'm not going to have you read books upon books with observable evidence (and evidence that can be observed by anyone else with the inclination to do so)

A super natural force (does not necessarily have to be God, maybe we're all wrong and it's something totally different) is beyond what we can even comprehend. He/It MADE science. Science could not have created itself, that makes no sense.
I will believe in the big bang when someone manages to create a live animal out of nothing. You demand proof of God, well I'm going to play that game too and demand proof of the big bang.
wtf kind of idiot thinks that the Big Bang has something to do with abiogenesis? Abiogenesis provides zero support for the Big Bang. Zero. None. Even if we created life in a test tube every day, it provides ZERO evidence for the Big Bang. Again, you're making yourself look incredibly ignorant - willfully ignorant, like someone sticking their fingers in their ears going "lalalalalala" for years. But, there is a shitload of evidence for the Big Bang - much of that predicted by theory and later found, such as the cosmic microwave background radiation. Discovery of the CMB is akin to the discovery of a fossilized dinosaur bone. If you found the femur of a t-rex, would you continue to declare that the t-rex never lived? i.e. would you claim that God buried the t-rex bones as a giant joke to test faith? If so, then the CMB is a giant joke to test faith. Or rather, test the faith of a particular narrow view accepted by only a subset of Christians. Again, it's worth point out here as I've done in the past, EVEN the Catholic Pope has said "yep, those scientists have so much evidence for evolution that it's considered fact. Ditto the Big Bang." The Catholics don't have any hangups about either proving that God doesn't exist - again, it's only a narrow subset of Christians who see either theory as an attack on religion. What IS important though is that society prevents their counter-attack from derailing scientific investigation and further progress.
Then why do theories of universal expansion have it eventually shrinking?
Back in roughy the 1970's, there was the question: will the universe keep expanding? Will it's expansion be asymptotic - reaching an equilibrium? Or will its expansion slow down and gravity pull the whole thing back together in a big crunch? The level of precision in observations wasn't good enough to answer this question back then. However, it's since been answered, and it's not going to eventually shrink. (In fact, its expansion appears to be accelerating.)
