It's not a fair analogy. The threshold of scientific proof is a much higher than the threshold of evidence you are relying on to believe in God.
Yes, it is possible that one day science may evolve to a point where the existence of God can be proven, but the logic doesn't follow that just because that possibility exists then it will be realized.
Right; I don't want to try to talk you out of believing in god, because I rather would like there to be one; however, in every single example you listed, the scientific method allows us to question, examine, deconstruct, reconstruct, test, evaluate, reevaluate, debunk, undebunk, redebunk, unredebunk, test further, manipulate, regurgitate, et cetera. No faith is really required because we can TEST the nature of the universe. God isn't offering anything for us TO test, so he does require faith... which is not to say, religion (which I've come to discover is about as anti-faith as one can get ,assuming one gets too into it, by definition.) I.e. religion: Hi... believe X, Y, Z or you're evil and we have all the excuse we need to hate/rape/kill you. This is a bit over the top... except when it isn't, of course. People do crap in the name of anything they gosh darn please, so it's not really religion I blame there. The true point was that if a religion requires a certain core set of beliefs, then it goes against faith which is 'trusting without knowing.' If you 'know' something, you don't have to have faith in it. So I separate the terms simply out of simplicity.
As a side note, I get irritated when people automatically disregard something that is in this 'theory' stage. Well, it's only a theory, right! It has no basis in fact. It would be hilarious if not for how much damage this does. Gravity is a theory. It's also an observable fact. We just don't know, for certain, how or WHY yet... the THEORY part is our trying to explain this observed fact.
As for god; Let's hope. And have faith that things'll work themselves out, even if we all go extinct in the process. What is, is, so there's not too much point in worrying about it so long as we each do our best and try not to be so gorram evil all the time. Just please don't be surprised if, upon discovering the true nature of god, it isn't what you or I or any of us expected. =3 I still can't escape the impression of the old testament as the 'spanking' a toddler gets... a toddler who simply doesn't even really understand language yet, and still must be disciplined, warned away from wandering into the road even though we can't know why, yet. SPANK. FEAR, PAIN, etc. Then comes the new testament for a child race who is starting to comprehend the world around them... who has language now (of a sort, I suppose) and can begin to hold a dialogue and think things through, but not quite to the level yet where the complexities of reality can be properly digested. So? Welp... birds, bees, storks, santa claus. We're given the gist without the gall, patted on the head, etc. I just can't help feeling like there are more testaments coming for when we come of age, enter the work force, have our midlife crisis, retire, et cetera.
