what do you call a religion without god
Nontheistic religion Nontheistic religions are traditions of thought within religions—some otherwise aligned with theism, others not—in which nontheism informs religious beliefs or practices.[1] Nontheism has been applied to the fields of Christian apologetics and general liberal theology, and plays significant roles in Hinduism, Buddhism and Jainism. While many approaches to religion exclude nontheism by definition, there are some inclusive definitions that show how religious practice and belief do not depend on the presence of god(s). For example, Paul James and Peter Mandaville distinguish between religion and spirituality, but provide a definition of the term that avoids the usual reduction to "religions of the book":
God (word) The English word god continues the Old English god (guþ, gudis in Gothic, guð in Old Norse, god in Frisian and Dutch, and Gott in modern German), which is derived from Proto-Germanic *ǥuđán.
