All knowledge and facts are beliefs, the rub lies in the justification.
Knowing that 2+2 = 4 or the the speed of light in a vacuum are objective, observable facts that can be proven.
Believing in an invisible sky person that loves foreskins, grilling out is not.
Are you attempting to place those things on equal footing?
An odd postition for someone who enjoys evidence so much, but hey, philosophy isn't everyone's bag.
I'm very interested in useful philosophy. Do you have any of that?
