(Non-Polemical) What do you believe, and why?

In general, about religious, philosophical, theological topics etc. What do you believe, and why do you believe it?

I'm just curious. This isn't a scientific survey, or a polemical debate sort of thing. I'm just interested in seeing what people's answers are.

If you'd like to follow up on the history of how you came to believe what you believe, such as university classes, books, teachers, peers, or "always believed it" etc. that would also be very interesting to hear about.
