Whether the gods are objectively real is the least interesting question you can ask about a person’s religious experience. What is much more interesting is the subjective reality of their experience. What was the experience was like for them? And what does it mean to them in the context of their life? People’s religious experiences aren’t going to help us put a person on Mars or cure cancer, but they can help us understand why we want to put a person on Mars or why should try to cure cancer.
