These conversations tend to start off on the wrong foot because people see religious belief and rationality as being at odds. They're not; they simply exist in entirely different realms of thought and experience. Of course religion isn't going to stand up to science in a debate based on logic and empirical evidence. Religion is irrational and subjective, though in this context those words are not synonymous with "false". They are different methods of seeking specific types of truths, and neither is more important than the other. This is why I take issue with certain Christian beliefs as well, like those "Christian scientists" saying that the earth is 6,000 years old. That's religious thought making a failed attempt at existing in rational terms, whereas what you're doing is trying to force rationality onto the ineffable and immeasurable experiences of spirituality. Rationality and spirituality. Logic and myth. Science and religion. The ancient Greeks of course referred to these as logos and mythos, respectfully.
The kinds of questions we explore in each of these methods of obtaining knowledge and wisdom are different from one another. Science may ask, "How did life come into existence?" while spirituality may wonder, "For what purpose does life exist?"
Again, it is a mistake for religion to proclaim that their truths are scientifically true. In saying that "Adam was created of mud and stone," a creation myth is not meaning that's what literally happened. Myths are written in the language of symbolism, metaphor, exaggeration and deep emotion. To interpret them in the realm of reason misses the point entirely.
I've been watching some interesting Dawkins stuff on youtube today, and something that really struck me was that at one point he said that wondering about the purpose of existence is simply an invalid question. He likened it to being ridiculously curious about the color of jealousy. And he's totally right, within the confines of rational thought there is absolutely no reason to ask such questions. Moving out of that place though, we find that jealousy is green and purpose can be an unexplainable religious experience.
