Good point.

Many of my religious friends say they KNOW there is a god because they have felt something spiritual. But these "spiritual experiences" are explainable today by the latest research in such fields as neurobiology and neuropharmacology. Having a "spiritual experience" doesn't prove God exists any more than swimming in the ocean proves Poseidon exists. I've had experiences of oneness and connectedness so I know what they feel like, and I'm guessing these feelings may be responsible for the invention of religion in the first place back when Homo sapiens was evolving.
