Dealing with existential nihilism

[Neo-Scholastic]

If there are thousands of different gods that people strongly believe in, then what's the most likely position?...billions of others think each other's God is made up.  I think theirs is made up.  They think mine is made up.  So clearly one's cultural beliefs, one's religious experiences or feelings, and one's logical attempts to justify them cannot establish the truth of a religion.

Personally, I'm not seeing the problem here. MK and I do significantly differ with respect to the special revelations we accept. And yet when I read the arguments and observations he brings to the table, these are nearly always based on general revelations of the divine with which I agree. I see nothing wrong with the idea that God meets us where we are (in this fallen creation) and would expect Him to take into account the culture and temperaments of those He is trying to reach. Ultimately, religion is about loving God with all our being and loving others as we would love ourselves.

This particular objection, that religions have various doctrines, is the flip side of TrueBelievers where uncertainty and indeterminacy cannot be tolerated. For example within Christianity, some doctrines, such as the Resurrection, are nearly universal. Meanwhile, other doctrines, such as eternal conscious torment versus annihilationism, are indeterminate. I have heard good arguments on both sides. It makes for interesting inter-Christian debate but is not a great source of division. Similarly, MK and I have different views on the authority of the Koran versus the NT Synoptic Gospels, Pauline letters, etc. I have heard arguments on both sides and have come down on the side of the NT. That in no way lessens my respect for MK or gives me cause to doubt his sincerity, just as I do not doubt your sincerity.
