In 2007, Dan Dennett spoke at the AAI conference about the difference of believing in God and declaring the belief.

He starts his talk with the following:

Long, long ago most people really did believe in God. Some people still do. I talk about the basic, primitive phenomenon of belief, like the belief that Mount Everest exists.

Just straight, ordinary, everyday, uncomplicated, belief in a proposition. Now, you can believe that Mount Everest exists and not know a lot about Mount Everest.

However, when presented with four pictures of mountains, I doubt that you’ll recognize the right picture.

But that doesn’t disqualify you from believing the proposition that Mount Everest exists in the first place.
