The Impossibility of an Explanation

i've seen many arguments put forward where i don't see that premises are true, doesn't mean the argument therefore is unsound. I think it's helpful to think of arguments as outlines, invitations to further exploration. So everything hinges on that first premise, which was that a imperfect or limited contingent can have an explanation. And so if there is an exception, we need some explanation of the impossibility an explanation. This would be a sort of a challenge for the viewers. Can you come up with a good explanation? D maybe you can of why there couldn't be an explanation of the the universe understood as limited, non maximal things. Ok?
