Which term describes the viewpoint that denies the existence of a god or gods?

The term that describes the viewpoint denying the existence of a god or gods is "nontheistic." This term encompasses various beliefs that do not adhere to the concept of a god or deities. Nontheism includes atheism, which explicitly denies the existence of deities, as well as agnosticism, which holds that the existence of a deity is unknown or unknowable. By contrast, theistic viewpoints affirm the existence of at least one god.

Theistic beliefs typically involve worship or acknowledgment of divine beings, while polytheism specifically refers to the belief in or worship of multiple gods, each possibly representing different aspects of life or nature. Monotheism, on the other hand, is the belief in one singular, all-powerful deity. Therefore, nontheism stands in contrast to these concepts by explicitly rejecting the notion of divinity.
