wtf happened before the big bang?

[Mr. Clandestine]

The Big Bang theory describes that the universe was once a very small, infinitely dense singularity, from which the observable universe we see today expanded from and evolved through a series of chemical and particle interactions.

Granted, but since there is absolutely no explanation as to how this infinitely dense blob of matter just happened to appear in the middle of a great void of time and space, we'll just have to admit that we simply don't know what we don't know. Hence the reason the "Big Bang theory" is still a theory, it's still plagued by large amounts of speculation. Until science can definitively prove that this matter existed in the beginning, there is reasonable cause to reject the underlying hypothesis... because for the most part, we can't accurately describe what we don't understand. We can throw in all sorts of conjecture, based on more speculation about the random observable facts that we can see... but that still doesn't verify the theory.

We can infer everything we know about the Big Bang theory from observable evidence we see today - the exponential expansion of the universe, the cosmic background radiation, abundance of light elements over heavy elements, etc.

You're right. You can infer that this observable evidence directly correlates to the occurrence of a Big Bang. But, you can't explain where the infinite amounts of energy originated that blasted this matter forth into the universe... you can't actually observe the universe as it expands... you can't explain why the dispersed matter is "clumped" together as opposed to having been evenly distributed... and you can't actually determine which elements are more abundant. You can only speculate, and you should know that this is not science. This is actually where I find many purported "scientists" begin to dig around the realms of metaphysical explanations, and this is where they lose all credibility of actually being called scientists. There are also several other theories that just as accurately describe how this "evidence" could point out our origins, but they're equally as speculative. And now that we've got these great thinkers like Dawkins drooling over mathematical consistencies and spewing forth long-winded explanations, the Big Bang theory is just the most overly hyped fad of todays 'evolutionary scientists'. Nothing more. In another thousand years, if our world still exists, I have no reason to believe that this theory won't have become outdated and replaced. But in a thousand years, again... if we're still here, I have plenty of reason to believe that the opinions of a Christian will have remained unchanged.

One can easily assume that the Big Bang expansion is simply God's method of creation rather than rejecting the theory all together.

One can just as easily assume that the expansion is based mostly on intangibility and hypothetical scenarios that best "fit" the intended theory. Denying this doesn't make me ignorant of the facts, because for the most part, there are none that directly correlate to the proposed theory. As long as we're free to speculate, you have no authority to tell me that I'm wrong. Likewise for myself.
