"I can't see how it could be possible to have evidence for or against god. Anything could be explained as the actions of god and anything could be explained as the as yet unknown natural laws of science."
You can't see because you aren't looking. Evidence is direct experience, to start with; scientific evidence is stated in words, that correspond to factual accounts, measurements with external equipment (except you have equipment too, built in. You wouldn't be able to do any external measuring if you didn't have "god-given" senses).
"Seeing how" isn't the same as seeing, is it? What you mean is you can't explain how or why God exists; you can't deny it with scientific reason (check out what Newton actually said, try to ignore the hyperbole and put his words into a modern cosmological context).
Faith is a tricky customer. We say we know what faith is, but then we can't really put this into words except very vaguely; almost to the extent of meaninglessness. However, saying what faith is and having it aren't the same thing either.
I think of faith like this: I have faith that I will wake up if I fall asleep.
However, I can't really believe this will definitely happen, I might stay asleep (in a coma, say), or die for some reason I haven't considered. Faith in my ability to wake up, is based on my experience of having successfully awoken many times, after falling asleep. Unconscious faith doesn't make sense at all; it's definitely a conscious act, having faith (in anything). Can you believe anything when you're asleep?
More to the point, claiming that nobody can provide evidence of God's existence/non-existence, is incorrect and unscientific. Can you think of a scientific experiment that would do either? What would be recorded and how? What kinds of instrumentation would be used, and could an experiment use ONLY human subjects and a vocal record (which would be: anecdotal personal experience)?
Have any experiments been done (to investigate "God" or otherwise) in this manner, devoid of "scientific equipment", and relying completely on human perception?
(Well, yeah... quite a few in fact, have been.)
