'''Strong atheism''' (sometimes called "positive atheism"), an offshoot of [[atheism]], is the absolute doctrine that [[God]] does not exist. It is different from [[weak atheism]], in which the believer claims only that theists cannot prove there is a God, so the atheist is justified in not believing in God.
