"This is almost a syllogism, the most basic and widely accepted standard of logic, saying that salvation cannot come through things that are seen. Since science deals with the realm of things that are seen, and logic uses syllogisms, then using logic to think about Christianity means that scientific fact(? what do you even mean by that, anyway?) isn't a part of it."
Pure logic cannot assume anything. It can only list possibilities. So, if man is, and if man perceives, he can supposedly begin to list possibilities as to what also is. If a man perceives earth, he is not questioned. If a man perceives that he has feeling, he is not questioned. Yet if a man perceives God, perception is suddenly discredited.
If perception is discredited on the basis that many do not perceive the same thing, then specific feelings of the individual may also discredited, along with individual memory of events. If the individual is discredited, and you then discredit all like-thinking individuals, you discredit the entire concept of perception being reliable on an individual or group basis. An entire group can be wrong. If the perception of every member of an entire group can be discredited, perception on the whole is discredited. If perception is discredited, how are you to perceive that you are? Summarized, pure logic cannot assume, credit, or discredit. It can only list endless possibilities.
So, if someone says that they believe something because of what they have perceived, they should not be discredited on the account of "logic". Logic dictates nothing. On the other hand, if someone perceives God, he has no reason to believe otherwise, especially when backed by others. If instead of perception, this was simply an opinion, or concept, still nothing can be undermined by logic. Only the rules that man has perceived over time can try to discredit. These rules, according to logic, could change at any time, and are really just predictions based on previous fallible perceptions.
Continuing to ramble on, the most likely thing according to logic is that things will be unpredictable. So rules based on perception are never truly reliable. If the most likely thing predicts that the "rules" we perceive are unpredictable, then WHY IN THE WORLD WOULD YOU WANT TO USE THESE RULES TO DISCREDIT ANYTHING? Specifically perception on a group basis that they have perceived something outside of those rules?
So if God is perceived, I have no reason to distrust the idea. Especially when perceived by a large group. If he is a concept, he is just as possible as anything else. The only things that could say anything else are not reliable. So if you firmly believe that something is not, then you are even more illogical than the person who says something is, or that it may be.
