Why not deism?

[EgoDeath]

That's probably why we can't be just "theists" based on pure reason; there has to be some faith there, some revelation.

Well, even deists are operating on faith.

I don't think a complete idea of the supernatural is necessary for deists though, if it's only a very minimal rejection of naturalism. There is some supernatural cause, we don't know what, and we have no epistemological method to test a hypothesis. It is not strictly necessary to know what something is to know whether something is. We could argue that we don't really know what anything is, only that something exists and looks like stuff.

The difference between god and actual phenomena we know exists but don't understand, is that we actually have objective, verifiable evidence of those phenomena. We're far from understanding what black holes are, but we have plenty of evidence they exist. For god? Not so much.

Thinking of it somewhat differently, we wonder why things are the way they are. What does it all mean? Deism allows for some meaning or reason, even if we'll never know.

Even asking why is nonsensical. How is a much more important question.

And god doesn't necessarily provide meaning in people's lives. And people who don't believe in god are not devoid of meaning. If anything, my stakes are much higher than yours. You think you're going to live forever after your human body dies. I don't. I have much more reason to enjoy my time here on Earth, spend time with my family, do things I enjoy and chase passions that make me who I am as a person.

I don't need some idea of god for life to beautiful. Life is beautiful enough by itself. There's no need for fairy-tales.
