I think it is very important to polarize this debate into two seperate issues:
- What do Science and Religion make claims to? (What are their repsective “domains”?)
- What do scientists and religious individuals make claims to?
One is an issue of epistemology and positivism, the other is an issue of objectivity and fallability.
(This is so cool, I never get to epistemology in casual conversation…
)
Tackling the second issue first, I think part of the problem is individuals, whether consciously or unconsiciously overstep the bounds of science and present it as science, when clearly it is not. A theory or paper that has first been presented to a journal for peer review is no more “scientific truth” than a bill on a congressman’s desk is a law. The problem is we can all agree (in some cases) when something isn’t yet scientific truth, but declaring that something is is a much trickier proposition (there is no scientific congress to vote something into law, or scientific president to veto or sign a theory into “truth”).
At best, something gains general acceptance by the scientific community as “true” if it agrees with all known experimental observation, until such time as new evidence to the contrary surfaces. Implicit in the scientific notion of “truth” (and, I would debate whether Science ever truly claims to have “truth” or merely puts forth the best model of observed phenomena) is the presumtion of fluidity: “If you discover evidence “E” which contradicts “X”, then X is no longer true.”
Perhaps it is an inherent limitation of each respecitve discipline that when confronted with “E” and “X”, Science simply shrugs and readily discards the old “truth” (again, I’m not sure that the notion of static truth hasn’t been imposed from the outside), whereas fundamentalist Religion I believe (feel free to correct me with my apologies in advance) would respond “X is Cannon, therefore E cannot be true.” Many would find Science’s readiness to change its fundamental “truths” overnight very disconcerting, whereas others find Religion’s dogmatic adherance to “truths” which appear to be contradicted by observable evidence to be equally disconcerting.
In part, I believe the fault comes from us expecting too much from Science. Here is how I belive one of the aforementioned questions posed to a Scientist ought to go:
*TM: How did the universe begin?
Mr. Spock: There is not enough data available to draw a definitive conclusion.
TM: Dammit Spock, that’s not good enough! I need answers! Speculate. Give me conjecture. What’s your best guess?
Mr. Spock: Based upon the available evidence, it would be reasonable, based upon observed phenomena such as the three degree background radiation, current matter density in known space, …
<TM glazes over>
<TM taps foot impatiently>
TM: Get to the point. What’s the point of having a Science Officer if you walk me through the entire process before giving me the final answer?
Mr. Spock: …to conclude that all matter, and the space it occupies originated…Sir? Implicit in the “final answer” are the observations and procedures which were used to obtain it. I can give you objective measurements, such as the charge of a proton, as fact within a margain of error, but as for the conclusions drawn from those facts, I can only give you the best hypothesis available which agrees with all known evidence. If I simply “give” you the answer, it would be imprecise.
TM: Spock, when I want a lecture in philosophy I’ll ask for it. From now on, when I ask you a scientific question, I want you to respond with the most likely theory based upon all available evidence without any epistemological disclaimers. Is that clear?
Mr. Spock: That would be imprecise.
TM: That’s fine. I don’t have time for all the details, I need big picture.
Mr. Spock: But then there is no way for you to know the varying degrees of certainty behind any given “best” theory.
TM: SPOCK! ANSWERS! N-O-W!
Mr. Spock (clearly disgusted):A big “bang.”
TM: THANK YOU! <sighs> Now why…
Dr. M: **Dammit TM, he’s a Scientist, not a Theologin.

Sorry…I thought (hoped) that might be more amusing than the pedantic discourse I almost committed. The content is more or less the same. (Extraction of meaning is left as an exercise for the reader.)
I know personally, when I’m trying to impress a woman by explaining the emmision spectra of transition metals, I don’t ordinarily preface the conversation with a disclaimer about the known limits of quantum theory, the incomplete state of our scientific knowledge, and the limits of what Science can “know”. If she thinks I have Perfect Knowledge of Absolute Truth:
a) whose fault is that anyway?
b) who am I to disagree with such a charming young woman?
Am I being an irresponsible scientist?
Maybe.
Do I get invited back to more parties than the guy who is still explaining the conceptual roots of Positivism?
Heck yeah. 
Is it generally understood that I’m just giving the best current theory for all known data and nothing more?
If it isn’t, it should be now.
I hereby renounce all future moral responsibility for anyone mistaking Science for Truth.
I’ve gone on too long already, so I’ll save the ramble on True, False, Unproven, and Unproveable and the OJ analogy for another day.
