Regardless of that Logos is not equipped to answer these questions...
Logos wouldn't really answer the question but provide a framework by which the solution can be found.
Completely oblivious of this type of thing, it is equally weak argument to say that becuase Logos cannot prove its existence must mean that you are stupid to believe in it as it is to say "I feel it so you are stupid for not believing!"....
I haven't called anyone stupid for believing in things, I have just asked them to challenge WHY they believe things and what makes them believe.
If the reasons are based on pathos, for eg because belief provided comfort or it is mere feeling, I have challenged them about the strength of that argument.
Demonstrating the fallacy of religion goes much further, into helping people understand how and why they adopted such beliefs, where the beliefs originated....
