I believe in God, I just don't believe in religion. It's a problem of scalability, and religions just don't scale well. As one person put it, "The farther you get from Jerusalem, the sillier religion becomes." And by the time you reach the stars, religion is downright hysterical. So we have a conundrum, one that is, to my mind, resolved by recognizing the principle of self-organization, that is, the universe self organizes into an order defined by the physical laws of that universe. It is that principle that explains how, in a demonstrably, measurably, entropic universe, we can be here, having this conversation.
Randomness, another thorny problem, is simply order on a scale beyond our comprehension or capability to calculate. Shooting a single pool shot is simple enough to calculate and execute to make it a game. Breaking a rack of 15 balls, for all practical purposes is random in aggregate. Each interaction between balls, felt, and cushion; the associated coefficients of friction and elasticity, geometry and gravity, can be individually calculated but the resulting transfer function of the whole rapidly becomes impossible due to minor variations - the butterfly effect.
And so it is with our favorite topic here, acoustics. We all get direct sound, a trnsfer function of the speaker into the listening environment, but the transfer function of the reflected sound is vastly more complex, beginning with early reflections, then secondary, and tertiary reflections before we throw up our hands an call the aggregate sum of all non-direct sound "reverberation" the character of which our brain uses to assign size and subjective quality of the listening environment. My mentor, an acoustical physicist and architect once tried to define the transfer function of a concert hall on paper. After 20+ pages of equations he came to the conclusion that an approximation adequate to fool the ear was possible, but even small variations in parameters could lead to huge unexpected - and audible - variations. In complexity theory, this modeled in part through, among other means, the General Logistics Equation.
Bsck to the questions of God, and life. It follows from the Principle of sel Organization, that life is an eventuality, given certain preconditions. And sentient life is simply an even more 'random' example of that eventuality. Creating religions in an attempt to explain that phenomena is to ignore the greater story, and the uniqueness that is, for better or worse, ourselves.
