History of atheism

Atheism is an absence of belief in the existence of deities. In a narrower sense, atheism is specifically the position that there are no deities and any statements to the contrary are false ones. The English term 'atheist' was used at least as early as the sixteenth century and atheistic ideas and their influence have a longer history.

Philosophical atheist thought began to appear in Europe and Asia in the sixth or fifth century BCE. In ancient Greece, playwrights expressed doubt regarding the existence of gods and the antireligious philosophical school Cārvāka arose in ancient India. Materialistic philosophy was produced by the atomists Leucippus and Democritus in 5th century BCE, who explained the world in terms of the movements of atoms moving in infinite space.

The Enlightenment fueled skepticism and secularism against religion in Europe.
