We are talking about extraordinary claims requiring extraordinary evidence. I don't ask for evidence if someone tells me they drove to work today, but I WOULD require evidence if they said they flew to work on a dragon's back!
My analogy is not off at all.
Someone professing to believe in some divine being is not making a claim but a statement of faith, which is no different at all from accepting that you drove to work (or flew a-dragonback).
Belief itself is not a claim.
Here's the difference:
"I can fly by flapping my arms" is a claim, and is perfectly testable through the scientific method.
"I believe Joe can fly by flapping his arms" is not in itself a claim. It's a statement of faith
about a claim. While the embedded claim is testable, the statement of belief itself, not being a claim, must ultimately be taken on faith (or disbelieved on the very same basis.)
A statement of belief is entirely kosher so long as what evidence exists outweighs the threshold of credulity. This threshold varies wildly by the individual and the context.
If you tell me that you drove to work today, fine, I have no reason to disbelieve you, so I'll probably take your claim on faith.
But if Ray and Egon tell me they saw you hanging out at the pool hall, and your boss calls to find out if you're okay since she didn't see you at work today, my threshold of evidence will go up, and you will need to present considerable evidence to earn my belief.
If, however, you were my best friend, I would likely take on faith that you weren't lying to me, and would likely believe you regardless of the evidence (up to the point where I didn't really care where you were today, anyway.)
One claim on your part, three contexts, and three vastly different, yet all perfectly reasonable standards of evidence on my part used to evaluate your claim, depending on context.
This is why "I believe in a god" is kosher while "God exists" is not, in terms of skepticality. The former is a statement of faith. The latter is a claim. Science and skepticism concern themselves with claims, not belief.
