And now in order for me to continue my side of the discussion, I have to divulge certain deep personal beliefs that are niether provable nor disprovable. Should I save us each the time and say we agree to disagree? Or bear some deeply personal beliefs to a FFVII Modding Community lol. I beleive that if one were to dissect the chemical reactions you speak of, down to the smallest level, that we would in fact become quite confused - because I beleive that we would be able to witness two identical (at least according to our perception) events that are capable of producing different behaviors/thoughts/feelings. Without the ability to observe these actions from a God-like perspective (the type of perspective you described earlier in the thread) we would not be able to make any sense out of it. Basically, there are natural laws, and then there are supernatural laws. The realm that man resides in and the capacity for man to percieve and comprehend this realm are limited. If we had perfect perception of reality and perfect understanding, it would still be limited by the fact it is only this Universe. If I have 100,000,000,000,000 x 100,000,000,000,000 Perception/Understanding Points, it is still 0 points when compared to the infinite.
Of course we have no way of proving this, the very idea prohibits finite beings from being capable of proving such things. A decent analogy would be vision. We see everything in the visible spectrum with our eyes, but thats all we can see. Using only our eyes, we could never hope to see radio waves, x-rays, infared, etc. We design technology to translate these things into something we can actually see...but its only a translation.
As far as good and evil, religion spirituality blah blah goes...without some higher power, good and evil are totally subjective (depending on your views of the conscience/innate morality). Keep in mind, I don't subscribe to any traditional notion of religion or God - to me scientific law and God are not mutually exclusive. Creationists are dumb because laws exist. Scientific Purists often act like the existence of science somehow disproves God...I don't see why science isn't simply a language spoken by God that we are capable of understanding. For an infinite being to communicate directly would obliterate the universe (or something), science is merely a means of interpretation.
*I don't mind the edits at all. I just wrote a response only to discover that I hadn't addressed each point because points had been added lol.
