Atheism: "in general, the critique and denial of metaphysical beliefs in God or
spiritual beings. As such, it is usually distinguished from theism, which affirms the
reality of the divine and often seeks to demonstrate its existence. Atheism is also
distinguished from agnosticism, which leaves open the question of whether there
is a god or not, professing to find the questions unanswered or unanswerable."Encyclopedia Britannica.
