u/dont_know_whats_real

I am writing a character that believes that all religions are true in some way, including atheism. They do not believe that there is a god, but they do believe in a higher form (but they know for sure it's not a god). If someone were to ask them what their religious view is, they would say they're neither a theist nor an atheist, but I'm looking if there's a singular word that describes this thing better. Thank you.
