proof of the existence of god (OT, of course)

Pantheism is the view that the Universe (Nature) and God are identical.[1] Pantheists thus do not believe in a personal, anthropomorphic or creator god. The word derives from the Ancient Greek: πᾶν (pan) meaning ‘all’ and θεός (theos) meaning ‘God’. As such, Pantheism denotes the idea that “God” is best seen as a way of relating to the Universe.[2] Although there are divergences within Pantheism, the central ideas found in almost all versions are the Cosmos as an all-encompassing unity and the sacredness of Nature.

Polytheism is the belief of multiple deities also usually assembled into a pantheon of gods and goddesses, along with their own mythologies and rituals.

Polytheism was the typical form of religion during the Bronze Age and Iron Age, up to the Axis age and the gradual development of monotheism or pantheism, and atheism. It is well documented in historical religions of Classical Antiquity, especially Greek polytheism and Roman polytheism, and after the decline of classical polytheism in tribal religions such as Germanic polytheism or Slavic polytheism. It persists into the modern period in traditions such as Hinduism, Shintoism, Chinese folk religion, etc., and it has been revived in currents of Neopaganism in the post-Christian West.

Polytheism is a type of theism. Within theism, it contrasts with monotheism, the belief in a singular God. Polytheists do not always worship all the gods equally, but can be Henotheists, specialising in the worship of one particular deity. Other polytheists can be Kathenotheists, worshiping different deities at different times.
