so mortal religions he figures are all, you know, fine enough, but they're either completely fictional or based on like the pre-history fight against the Faceless Ones. the ship has expanded this belief into a general atheistic "that's nice, dear" viewpoint

as for his own people's religion, the Faceless Ones? FUCK EM. GET OUTTA HERE MOTHERFUCKERS, NOBODY WANTS YOU!!!
