A person who worships other beings is called an Idolater.

The term "Idolater" is derived from the word "idolatry," which refers to the practice of worshiping idols or other beings apart from a central, often monotheistic, deity. In many religious contexts, this means showing reverence to deities or objects that are considered false or secondary to a supreme being. It reflects the act of giving undue importance to physical representations or other divine figures, rather than adhering to the belief in a single, ultimate deity.

This concept is important in various religions, where the act of worship should be directed toward one main god, and worshipping other entities is seen as a deviation from this practice.
