Agnostic: Someone who cannot prove or disprove the existence of any deities/gods.
Although atheism is described in a variety of ways that often depend on the views of the describer, an atheist is a person from whose life a belief in the supernatural (God) is absent. There is no denial of, no failure to recognize and no denouncing of the supernatural contained within the term atheist. At its most basic level atheism is the absence of belief in the supernatural.
Every single person in the universe is agnostic even if they don’t say it. Some people are agnostic theists, meaning they cannot prove or disprove the existence of any deities/gods but they believe that one or more do exist. Some people just call themselves agnostic because they cannot prove or disprove the existence of any deities/gods & they don’t believe one way or the other. Theists, atheists & agnostics may or may not be religious. It is entirely dependent on the individual. Most religions are theistic, meaning they centralize around the existence of a god(s), however not all religions are.
