What religion would these beliefs fit into?
So , I don’t believe in God or the Devil/Satan hell whatever. But I do believe there is a life after death/spirit world …. whatever you wanna call it. Reincarnation and enlightenment.
I know there’s buddhist and Hindus. What else….
And i’m being serious.
Not just the christian god all deities.
Do you mean you don’t believe in the Christian God, or the idea of deity period? If the latter, then Buddhism is pretty much your only choice for atheism + reincarnation. If you believe in some kind of deity, then you have plenty of choices, too many to list. Some of the more common ones today are Hinduism, Jainism, Sikhism, Neopaganism (Wicca, Druidry, Asatru,) etc.
Additionally, some Hindus don’t believe in literal deities, but have a more pantheistic view of deity. If you can believe in the divinty of nature and see deities more like symbols than literal beings, then perhaps some pantheistic version of Hinduism would work for you.
