Define Atheism.

Atheism is a philosophical and ideological stance characterized by the absence of belief in the existence of deities or gods. Atheists, often referred to as non-believers, reject theism and assert a lack of conviction in supernatural entities. Atheism does not constitute a unified belief system; rather, it serves as a broad umbrella term encompassing various perspectives, including secular humanism, agnosticism, and skepticism.

Atheists typically base their worldview on reason, empirical evidence, and scientific inquiry, rejecting faith-based or religious claims about the existence of gods. The absence of belief in a divine being is central to the atheist position, and individuals may arrive at atheism through different intellectual, philosophical, or personal paths.

Atheism should be distinguished from agnosticism, as atheists tend to assert a lack of belief in gods, while agnostics emphasize the uncertainty and unknowability of such metaphysical claims. Atheism has a long history, with notable atheist thinkers contributing to philosophical, scientific, and social discourse throughout the ages.
