as for trusting in experts, there's no question that that is problematic in the extreme. However, it comes back to how the evidence rises to the claim. Can a group of people be experts in a subject? How can we validate that? Can we verify that their are experts in how electrical wiring works? To a large degree we can. We have lots of evidence. Do they know everything, probably not, but i can have confidence that they are mostly correct. Can we verify there are experts in evolution? Again, i think we can. They have produced mountains of evidence. Do they know everything? No. But they are likely largely correct. Can we verify there are experts in God? What are the tests? How do we verify these experts?
You mention faith, and i have to ask, what good is faith? Is there anything you could _not_ believe, based on faith? If faith has no mechanism to filter out anything, does it tell you anything about what is true or likely true?
