TRUE and FALSE are the issue here. No such thing. Everything is a belief, or a concept.
There is a lot that goes into 2 + 2 = 4. Sounds simple right? But the concepts of counting, addition, symbols to represent numbers, and what those number represent in the real.
2 is a generalization and abstraction for 2 things, but what those things are require our brain to interpret.
This might be simply as converting light hitting the eyes into a mental model. For example: The earplugs. Those earplugs don't really exist in any absolute terms. They are a piece of foam. So you might say you have 3 earplugs, and a flotation device for an insect. But ... you might also say it is a gazillion atoms.
My religion is "I don't know".
