Theism is a broad category of beliefs that encompasses the belief in the existence of a god or gods who are typically seen as the creators and sustainers of the universe and who may intervene in the world and the lives of humans. Theism can take various forms, including monotheism (belief in one God), polytheism (belief in multiple gods), and pantheism (belief that God is immanent in all of nature). Theistic beliefs often involve a relationship between humanity and the divine, which may include prayer, worship, and adherence to religious doctrines or moral codes. Theism has been a dominant feature of many cultures and societies throughout history, shaping religious practices, ethical systems, and worldviews.
