the crux of the argument is even for the atheist, it is necessary to take science on faith, as it is impossible to know and prove everything. we are placing faith in scientists that we will never meet, so why should we take issue with the religious who are placing faith in a god that no one can prove or disprove?
the most significant difference is that the god-faith is unchanging - the holy books are not going to be re-written. the interpretation of such are based on the religious leaders in power, and one only hopes they have the best interests of humanity in mind. science, on the other hand, does change all the time. every few decades, a major scientific "truth" gets overturned. science-faith is not absolute and is evolving all the time.
faith is often so badly abused today, and self-reflection drowned under a sea of noise. faith is precious, and should be used sparingly and in special occasions, rather than a safety blanket for us to wrap ourselves around.
