Atheism
This word comes from two Greek words, a the negator, and theos, God. Atheism teaches that there is no God of any kind, anywhere, anytime. Some atheists claim to "exercise no belief in a god" the same way they would exercise no belief in pink unicorns. Logically, an atheist would be an evolutionist.
The Bible teaches that all men know there is a God (Rom. 2:14-15). Therefore, they will be without excuse (Rom. 1:20 ) on the Day of Judgment. Instead, atheists willingly suppress the knowledge of God by their unrighteousness (Rom. 1:18-19).
