Science doesn't give answers immediately. And while you are largely correct, the mystery is not so great as is often implied regarding the beginnings of life and the big bang.
We don't have any well accepted theory (ah we must discuss this word better later) regarding the origins of life, but there are things we do know. Until we know more, there will be no working theory. For instance: we know that amino acids are a bit of a "step one" in the process. We know that when created in a lab, amino acids tend to be 50% left or right. This is to say that all amino acids can corkscrew in one of two directions: it may be useful to think of this as being clockwise or counter-clockwise as opposed to the nomenclature of left and right. Ours all turn one way. This is a big deal. . . Certain stars will affect the creation of these molecules to only turn one way-- but not ours. Is this significant? Yes. Does this explain the origin of life? Not at all. It is one seemingly random and insignificant piece to a larger puzzle.
We have many mathematically beautiful explanations for the big bang. People enjoy thinking of the big bang as "the start of it all" and then point to it arising from nothingness. This is not remotely the prevailing thought. At the moment, the likeliest explanation is when two branes (membranes, think of them as sheets wafting in the wind) "touched," they produced the big bang, and a universe, one of an infinite number. The simplified "I took 5th grade science" version is what is attacked-- not the actual theory as it stands in physics today.
This is all a bit here nor there for the conversation at hand, and unfortunately it is a very difficult subject matter to address until the more basic concepts are understood by everyone, as neither subject applies to evolution or creationism, but I just had to comment quickly. I'll get back to the main matter soon. :)
