Religions don't necessarily have the idea that faith as a trait is desirable. That very much depends on the religion.

However, every single day we make decisions based on not knowing. We make those decisions with the best available evidence at hand, both observable and non-observable. To wit, in your example I'd never drive on the interstate 90 to a non-existent destination, but you'd take the drive not knowing what you might encounter along the way; hence the road trip.

I can't prove the existence of a deity. Equally I can't prove the lack of existence. Today I can prove certain phenomena that in the past we were unable to prove. That didn't stop belief, it merely asterisked it.
