I'm not really sure what you meant then. It seemed like you were saying that scientific knowledge involved faith in it being correct, but I may have been too quick to jump on that. If you're saying we should all keep an open mind and be humble because we're all still essentially mostly ignorant and future generations will likely laugh at some of the things we believe, then we're in full agreement.
I must confess I don't understand religious faith. I wasn't brought up in it, and neither were my parents. I'd be willing to accept it a blindness on my part, if I saw some sort of objective proof that it gave believers anything that I lack. A colourblind person will be convinced of his condition because other people are clearly seeing something they're not, and they're always in agreement. No so with faith. On what basis can a fruitful discussion even take place when the issue is framed in personal experience and subjective feelings?
Religious liberals are harder to debate because they never seem to take a position on what exactly they do believe so that it can be discussed.
