Nihilist, insofar that even if there is a god (about as likely as me actually being a secret agent for moon people) why would it matter? While nihilism is not a religious belief I think it fits the prompt.

I made a poop the other day, I’m its creator, I don’t care about it, I don’t control its destiny beyond the flush.

I’m an optimistic nihilist, nothing matters and that’s kinda neato. Existence happens, how fascinating is that? It’s absolutely meaningless just like everything in the universe, but that doesn’t mean we can’t enjoy the ride.
