The proof you desire is abundant in the Bible.
I guess it’s impossible to discuss facts and reality with someone who always goes straight to faith and belief.
If you don’t see the difference between an actual God (if He exists) and a book about God (among other things), there’s no point in continuing. the Moby Dick analogy should have been a clue. Writing a book about something doesn’t prove its existence.
Last chance... “Hey God. If you exist, please show yourself to the masses. Don’t use a book, don’t come to someone in a dream, don’t use a burning bush, don’t use anything other than your actual self. Being all-powerful and creator of everything, surely you can pull off a simple feat like this, right? I humbly ask this of you because it hurts no one and nothing for you to prove your existence. Your failure to do so will be conclusive proof that current believers are no more enlightened than the believers in every fallen religion throughout history. So what’s it gonna be God? I’m serious. Are you real???”
Waiting...
