Faith CAN dictate your logic, and people DO have to believe in stuff being real in order to have discussions. But faith without proof is a burden on the person who can't replicate their miraculous claims. Until you can have God himself fly down from the Heavens and make another human being from clay, then you can't consider it scientific. I can't prove it DIDN'T happen, but that makes it more troublesome for you, not me, because I am not saying it ever happened and therefore your point is pretty much moot, despite your devotion.
For me it seems to make sense not to believe anything important enough to need analysis but have no way to analyze it. I suspend judgment on how a variable, such as the conceptual idea of God, might fit in, if it exists in any form. It seems more freeing this way because there is nothing really inherently good about being determined that you HAVE to be right.
