Does a chicken need a justification to cross the road? No it doesn't. It may prefer a reason but having a justification is not a prerequisite for it to function.
Just like we don't need to know the meaning of life or have moral grounding. Unless there is a pragmatic/useful reason it is purely cosmetic/philosophical.
We invented language, math, logic etc as useful tools to function better in life not because your particular god said so.
I am not interested in your interpretations of the bible either because at the end of the day you and I can dance back and forth on interpretation all day long.
I am interested in the physical proof that cannot be misinterpreted with sophistry and etymology. Either you have it or you don't. Throwing philosophical rabbit holes at the problem is a form of escapism.
because logic and reason can exist without you knowing or understanding it is actually evidence you are wrong with your position that logic, math, and language are useful tools and not universal. you simply have not justified them, meaning you don't know what they are, where they come from, how we can have access to them, and explained how we can know this is the case.
utility does not justify, using something is not justification of the thing. I can walk down the street, but that doesn't explain what a street is, how it came to be, and what its purpose is. you cannot come to meaningful conclusions while being arbitrary. you cannot know if Christianity is true or false, if we ought survive, if you can form meaningful sentences at all without justification of reason.
language, math, and logic are not universal and are only human inventions now? so logic itself is not universal, is this the new claim? does the concept of logic itself rest in a particular mind, but not mine? is this mind itself universal? how do we know it is reliable? how do we have possible relational knowledge of them in a particular way when they are themselves universal.
why should I accept your 'inventions' as a standard for reality? you can't use an 'invented' tool to demand 'physical proof,' because you haven't grounded the reliability of the senses or the uniformity of nature required to process that proof.
you call philosophy 'escapism,' but you are the one escaping the fact that you can't justify your own mind. you want 'physical proof' while standing on a foundation of 'unjustified axioms.'
