Good question. Perhaps you found the wrong one?
I mean there’s such a wide selection you can even believe in simulations these days.
Or if that’s still too much there’s always the Pascal’s wager God. Still better than nothing.
Why bother, though? What does trying to believe in this ill-defined entity do for me?
I find Pascal's wager is of the same nature as Aquinas' Five Ways to prove God, or accelerationists about the inevitability of a Singularity: believing that your own rational argument can be the basis to prove a fact about reality merely because it feels internally consistent.
Needless to say, I don’t find them at all convincing. This 'nothing' is much better than catching unconvincing unneeded supernatural entities.
