I shall attempt to answer the points of your post in a condensed, structured manner as opposed to quote-by-quote, this should be more space-efficient and easier to read in context of our arguments.
Regarding our knowledge of the leap from reason to faith, from one side of the rivine to the other in the absense of knowledge of a bridge. You raise an interesting point that the interface between faith and reason, if I may call it an interface is a subjective one. When I say subjective here, I mean it is subject both to individual interpretation and knowledge, society and general philosophical or scientific progress. If I were unaware of any arguments against God's existence, yet I regarded the pro-God arguments as insufficient I may either believe in God or be agnostic, since I would not have the grounds for atheism. I have the grounds for atheism now however, as a provisional scientific assessment. Now earlier I explained the remit for science, that which is categorically objectifiable, or empirical. It would be arrogant and frankly fallacious if I were to claim that science was even close to fulfilling its remit; it is not, be we can establish grounds for that remit hence my other arguments re. deity. This is why I do not agree with theories or statements premised by faith that present themselves in the scientific context. Remember that in science, the predicate for all knowledge is the statement "I don't know". But of course, regarding holes in science, that is no argument for deity, the proof by ignorance is a fallacy (lack of evidence for |= evidence against, at best it is an indirect, circumstancial indication, often mitigated by other things).
I am concerned though that by your final sentence on the topic, you were implying that inductive reasoning is lumped together with faith... I do not see that as so. Reason needs induction to make reasonable claims, since you're not saying anything Earth-shattering with 2+2=4. The soundness of inductive reasoning depends on external deductive factors subject to the context of consideration, but whereupon those are agreed, progress can be made, like in all arguments.
Now regarding trusting ones "sight" so to speak. As Descartes says it is not prudent to trust one who has previously deceived you. But then, to ignore that bypasses both faith and reason, the conclusion of which is Diogenes in his barrel or my solipcism. One makes presumptions that others exist and one attempts to interact with the world which of course requires reason and faith in one context, and faith in reason/reason -> faith in another. I should like the dilineate there of course, on the higher context where they are not dualistic it may be more prudent to compare it to love and logic, which as you may recall is a device I use often.
Now regarding evolution itself. Let it first be said that when it comes to debating I'm usually flexible and will change my mind when I know better, but that is more the case in science, I have no steadfast attraction to classical evolution. My concurrence with evolution is with the evolution of the moment, with special attention paid to the theory as it was after the work of Francis and Crick. Darwin's theory today, as he wrote it, has been largely superceded by it's modern descendants. It was a groundbreaking piece of science for its time, view it in the context in which it was written; a truly heroic piece of science and personal chutzpah, but Darwin was not a perfect scientist; he made errors and some of his other theories are regarded today by modern science as creationism is also. That we have greater control over our environment, a control subject to our whimsical intelligence and profound stupidity there can be little doubt. That accordingly we exert a control over our own evolutionary progress too is certain, perhaps now more so than ever with the advent of genetic modification/manipulation. You ask if we shape our environment, how are we subject to it? You answered that by mentioning an evolutionary feedback loop. It's not something Darwin could have possibly accounted for, he wasn't even aware of DNA. He couldn't have observed it in the Galapogos islands and it requires a widening of the notion of "survival of the fittest". But does any of this contravene the basic laws of evolution, as that theory is today (which you might more safely regard as an aspect of genetics more than anything else)? I do not think it does. Consider the analogy of the artillery piece and the rocket. The cannonball is subject to the laws of ballistics. The muzzle velocity, angle of launch, local gravitational field etc, will all effect flight path, flight time, maximum height, range, and all the rest of it. A rocket on the other hand is not bound by the same model because it has a source of onboard acceleration, control surfaces and what have you. It's flight path cannot be predicted by the same equation that governs the flight of a cannonball, however, does this now mean that it is not bound by Newtonian mechanics?
You say that a theory should not be adhered to as canonical even if the majority hold it as true, and I completely agree. Like I said, a theory should be judged by its merits, and should not rely on faith. You can read up on evolution and faith is redundant when concurring with it. That scientists do have faith in it, yes it's true. Do atheists have unnecessary faith that there is no god? Yes! (the lady doth protest too much). I maintain though that this is not an indictment of the theories, which are, after all, what we are discussing. They are an unfortunate consequence of having humans in the world. Few scientists are also philosophers, in my experience I would have no greater expectation of them to understand the philosophy of science or distinctions between faith and reason than a pornographer. However, if you'll forgive the digression, I think this error on the part of scientists is understandable.
Since the time of the inquisition, when science and natural philosophy was starting to encroach on the doctrine of the Church, science had been persecuted. It doesn't do ones psyche any good to be constantly ostracised for ones views or approach, especially when the people that do it act unreasonably. Couple that with general popular mistrust of the scientist, the intellectual and the technician and you'll see that some of these peoples lives must have been incredibly sad and lonely. Consider poor Galileo, I certainly don't envy his life. It is only natural therefore that they would get angry or bitter, and entrench themselves, and indeed it is easy when a theory becomes increasingly self-evident, against something like the Aristotolian model of the solar system or biblical creationism, that it's easy to justify and magnify the justice of your cause against your oppressors. From a modern, scientific point of view I don't think that this kind of oppositional polarisation is helpful, though it still continues on both sides, creationists denouncing and refusing to listen to evolutionists, evolutionists ridiculing creationists etc... but it's perfectly understandable. The best thing for us, as reasonable people able to rise above all of this, is to cut through a half-millenium of bickering and to judge the theory by its merits, it's validity, and not by those who have espoused it.
EDIT: As for the bible, yes I should read it but it's not convenient to do so at this point in time, if any passages come to mind that actually deal with (and not presume) the existence of God it may well be useful for the debate. At your convenience of course, I'll google in the morning.
