Faith is essential to both religion and science.
Explain please
Faith is a belief in something without evidence for it.
Science takes evidence observed in a continual present and uses it to try to make future predictions without any actual evidence of a future whatsoever.
Will you see the sunrise tomorrow (assuming you're an early-bird and also assuming I don't receive any complaints about the fact that the sun doesn't 'rise')? Do you have any evidence to suggest that it will, or only evidence that suggests it has in the past?
More than being essential to both religion and science, I think faith is essential to survival.
See...the science that I know says "it's likely the sun will rise tomorrow, but we can't answer for sure, because of the possibility that there will be an anomalous event, like an alien abducting the sun. Or it might just go out. But given what we've experienced in the past, and from the data we've managed to collect, our money's on the sun rising."
Does science rule out a more powerful, conscious being? No. In fact it says that somewhere, one should (but doesn't have to) exist. Based on the science I know, I do have to have faith that Math is absolute. But that seems to be it.
Math, and faith in accurate and/or comprehensive interpretation of real-world objects and events. Consider this -- a definition of a thing is essentially a theory of it. When researchers operationalize their variables, they are creating or reusing miniature theories of these variables. Not only that, but the variables themselves are miniature theories of the real-world things or events they explain. The whole process by which we cognitively know anything depends upon a whole chain of assumptions that could only be proven to be true if we could compare their past and future states. I just don't see, nor have I ever seen, concrete proof of a past and future. Actually, you could argue that there's evidence that suggests past and future states do not exist because the present is the current evidence we have. Even the theory of relativity seems to imply that individuals are only stratified temporally and that we basically all live in a relative present.
But on the whole, I agree with you. I just think religion and science have a lot more in common than people generally think.
Edit: I always found the following semantic musing interesting, though I admit its a stretch:
When I doubt, I don't know. (e.g. I doubt the Cubs will win the World Series, but hey, who really knows?)
If doubt is related to a lack of knowledge, does faith relate to knowledge?
