Not everyone has the intellectual capacity to be a scientist and realize that our understanding of the world is limited;
My response to that is that it's becoming obvious that not every person who claims they're a scientist has the intellectual capacity to be a scientist and realize that the theories that science has developed are based on those things that we currently know. Therefore, it is important that we never grow so attached to any theory that any questions about its validity, suitability, or completeness that we claim that a person questioning this is labeled as narrow-minded, illogical, or unscientific simply to protect the theory (or the process by which it arrived).
ANYONE - scientist or religious zealot - who says they know how life on earth came to be from the scientific standpoint is a quack.
No scientist today has proven - scientifically - the existence or non-existence of God. Nor has any person of faith. The belief in God is NOT in conflict with science, provided we ask the difficult questions: "If God was not directly involved, how did this come about? And if God WAS directly involved, what were the actual steps he took in the process to make it work - in other words, exactly how did he do it?" (And for the answer to the latter question, "He's God; he can do anything" is insufficient.)
You see, to me, God isn't some distant, unknowable force. I tend to think of him as - in normal everyday terms - a really sharp guy who understands how to do things, in a position of power where he can do them. You can find similar examples in your network administrator, your boss, a powerful political figure, etc. albeit on a much smaller scale. I don't see any reason we can't try to understand what he understands, or to try and figure out how he did the things that he did. But - just like your network administrator - I think he does set some limits - albeit reasonable, safe ones. (Your network administrator isn't going to want you unwiring parts of the wiring closet, trying to figure out how it works, for example.)
I would even argue that, from my perspective, the existence of God is necessary to validate science in the first place. If everything simply occurred randomly, according to no particular design or law, there is no point in trying to understand the universe, since some other random happening could come along and change all of the conditions. Even in terms of evolution, LIFE, not intelligence, survives. If radiation fatal to humans bathes the planet tomorrow, but fleas aren't affected by it, fleas survive and humans don't, regardless of the respective levels of intellect. Without a plan - a design - to understand, there is no point in science - it's a meaningless pursuit to understand a fleeting moment. Pursuing science is - to me - a pursuit to learn a little more of what God knows, and to understand a little better how he thinks.
