You litteraly said that
>Presup is the assertion that you can't have logic without God.
Lol.
>How can you know things
I know that I experience things, because I am experiencing things. I know that I can reason because I am doing so, hence I know logic exists.
>What about the objective outside world?
If the outside world didn't exist my mind would be all there was, I.e I would know all things. Hence it stands to reason that either the outside world exists or I know all things, I don't know all things, so the outside world is real.
So yes, I can know things without appealing to god.
Regarding divine revelation, a book coming from an unfalible source. I'm thinking about constructing an argument to prove that is impossible from what I showed above, but for now I'll just ask you to consider this:
Devine revelation from a book will be problematic for the simple reason that human language will always be ambigous, atleast in theory. If you find two seemingly contradictary passages in a holy book, or if your holy book seems to contradict reality, you will have to reinterpret your holy book, but you can always chose multiple interpretations, so which do you prioritize? If you want to claim it's self evident you will have to hold every person who choses a different interpretation to yours as a liar, or yourself as such. Moreover you will have to claim you lied to yourself before you changed your interpretation.
You can also not prove any other persons holy book wrong without appealing to your own holy book for the simple reason that any objection you have to their holy book can be answered by appealing to the fact that their holy book is right and that any seeming contradiction is no contradiction at all, it mearly appears as such, with the use of hermeneutics and appeals to poetic license any seeming problem goes away.
