Agnosticism after doubting my way out of Protestantism in my teens. Major contributing factors were my parents' divorce (which was clearly the right thing for them to have done, as one was abusive) and realizing I was queer
I'm split damn near 50/50 on whether I think a deity or deities exist. Physics observations that suggest our universe is a simulation, and weird things about consciousness (dreams, deja vu, near death experiences, psychedelic experiences, cultural parallels in seemingly isolated ancient civilizations, etc.) fascinate me and keep me wondering what might be "up there." At the same time, studying biology made me realize the "power" of randomness over millions of years to "create" what people find meaningful without there necessarily having to be divine influence. Typewriter-monkey-Shakespeare philosophical stuff.
I really, really hope reincarnation or a non-hell afterlife exist, though. I am TERRIFIED of oblivion. :(
