Apatheism

Apatheism (/ˌæpəˈθiːɪzəm/ a portmanteau of apathy and theism/atheism), also known as pragmatic atheism or (critically) as practical atheism, is acting with apathy, disregard, or lack of interest towards belief or disbelief in a deity. Apatheism describes the manner of acting towards a belief or lack of a belief in a deity; so applies to both theism and atheism. An apatheist is also someone who is not interested in accepting or denying any claims that gods exist or do not exist. In other words, an apatheist is someone who considers the question of the existence of gods as neither meaningful nor relevant to his or her life.

Apathetic agnosticism (also called pragmatic agnosticism) acknowledges that any amount of debate can neither prove, nor disprove, the existence of one or more deities, and if one or more deities exist, they do not appear to be concerned about the fate of humans. Therefore, their existence has little impact on personal human affairs and should be of little theological interest.

Apatheists hold that if it were possible to prove that God exists, their behavior would not change. Similarly, there would be no change if someone proved that God does not exist.
