Usage

What does atheism mean? Atheism is the belief that there is no supreme being or deity. In other words, atheism is the denial of the existence of God or of any gods. A person who holds such a belief can be called an atheist. The word atheist can also be used as an adjective to describe such beliefs or things involving such beliefs. The adjective atheistic can be used in the same way. The word atheism means something different from agnosticism, which is the belief that it is impossible to know whether or not a supreme being exists. When asked if God or gods exist, an atheist would answer “No,” while an agnostic would answer “It is impossible to know.”Example: Atheism isn’t the belief that God is bad—it’s the belief that God doesn’t exist.

Etymology

Origin of atheism

First recorded in 1580–90; from Greek áthe(os) “godless” + -ism; see a- 6 ( def. ), theo-

Explanation

Atheism is the lack of belief in the existence of a god or gods. Atheism isn't a religion — it's just the opposite. If you're fed up with religion or think that believing in God, heaven, and hell is silly, atheism just might be for you. An atheist doesn't believe in God or other supernatural beings. Some atheists state their belief more strongly, but it comes down to either "I don't believe in God" or "There is no God," which mean about the same thing. This is a stronger belief than agnosticism, which says we can't know if God exists.
