devotional practices for atheists, reapproaching religion

lately i feel drawn back to religion, and i’m wondering if there are any devotional practices for atheists/secular humanists

full disclosure i didnt grow up jewish, i grew up protestant, and am now an atheist with affinities for Buddhism, Hinduism, and Judaism but i’m surveying different traditions to see what they say.

put more clearly: i’m intensely interested in exploring the idea that instead of G-d creating us, that we created G-d, and how to proceed to participate with religion and religious practices knowing that it is a tool that mankind has created for ourselves and we can imbue it with meaning and find joy in the beauty of religious metaphor

also interested if anyone has any further reading theyd recommend
