What is an atheist and agnostic?

Atheism is, in the broadest sense, the absence of belief in the existence of deities.

Agnosticism is the view that the existence of God is impossible to be known or proven. The word “agnostic” essentially means “without knowledge.” Agnosticism is a more intellectually honest form of atheism. Atheism claims that God does not exist—an unprovable position. Agnosticism argues that God’s existence cannot be proven or unproven, that it is impossible to know whether or not God exists. In this, agnosticism is correct. God’s existence cannot be empirically proven or disproven.
