You have faith in your senses, how do you know theu aren't eluding you? You have faith in your memory, how do you know it is an accurate register?
I think this is the crux of many of the differences between people of faith and non-believers: many people absolutely do NOT have faith in our senses; understanding that our senses can and likely will fail us or deceive us. Many of us realize full well that our memory is not "an accurate register".
That's easy enough to understand and accept when you are looking at a scientific study that proves beyond doubt that humans (generically) have faulty memories or that humans' sense perceptions are often inaccurate. It's much more difficult to accept those facts and use them intellectually when your own personal cherished notions, perceptions and memories, are challenged.
