I’m not the person you responded to, but I can try to take a stab at that…

for a concept that prohibits proof as part of it’s definition, how do you determine that one faith (or system) is better than another?

Objectively, you don’t. But people’s experiences go beyond the objective, and we all have our subjective experiences too. Faith is how we make sense of those.

The question then isn’t, which one is better, but whose other experiences and faiths do we relate to? We build friendships and alliances based on those. Not because they’re better, per se, but because we feel comfortable or safe with them.

From that perspective it makes a lot of sense that we value other humans, because they can make us feel understood and appreciated, and we can exchange ideas with them which in turn refines our faith. Now, some people get tricked into thinking you can do the same with machines, but well, I think you can guess where I too stand on that idea.
