Your right, religion at times is very obscure but whether we like it or not it is apart of our heritage, and without a doubt will be part of our future, meaning, it will affect us in one way or another, whether it be throughout the world or even personally.
In terms of what proposed doctrine is right, I think, from an agnostic point of view, that it is indeed impossible to know whether god exists, or whether or not the belief in the science community-that evolution is the key to our origin. is correct. Given that both beliefs really are impossible too actualize, questioning of one's own belief would undoubtably follow in the course of one's own life. I have spent some time thinking of this in the past, I have looked at what other people think, from einstein, to hawking, to our great leaders, and I think we can all agree with religion has affected the growth of our world in one way or another. I mean the sole cause of any war is the difference in opinion, and it always alludes to some deeper seeded beliefs, ergo the differences in morality and thus religion. But for me, no matter what we do, or what we say, I feel it is impossible to derive such a profound answer to this question by the sole means of rational thought, I think you just got to believe what you got to believe. How can one argue with the opinions of such geniuses as Hawking (science), Einstein (faith, yes he believed in god), Da Vinci (science), or Gandhi(faith). The point is all these men were (or are) geniuses in their own respective fields, and their own proposes faith not only helped them, but all of us. I'm sure even they have their doubts sometimes, they just feel what they believe is right. So I guess what i'm getting at is we could use our rational brain for such an obviously philosophical question, but maybe we should do what they did, and do something that makes we are humans unique, feel, and then rationalize.
Anyways i'm going to leave off with a something I read awhile back that was interesting (i'm sure most of you guys have heard it) Paraphrase: "If you believe in god, and you were right, your going to heaven, if you believe in science, and you were right, you won't know you were right, if you believe in god and you were wrong, you won't know you were right, if you believe in science and you were wrong, see you in hell, so who get's the better deal?) - Not that this should be intended to change any views, but it is interesting to note.
I'm beginning to think religion is a fool's argument. You cannot prove or disprove the existence of something which does not exist, so what's the point? I suppose one could say that, logically, there is no reason to think that there is a god, but that doesn't often sway most theists.
