The term 'disbeliever in God' can be summed up as an ATHEIST, which is a person who does not believe in the existence of a god or gods. Atheism is a philosophical and religious position that rejects belief in any deity. Atheists may also reject other supernatural beliefs, such as the afterlife, miracles, and the power of prayer. Atheists may also reject the idea of a personal god, instead believing in a more abstract concept of a higher power.
