Defining Atheism in World Religion Atheism has numerous meanings and all of which are interconnected to a nonexistence of belief in the existence of a god, a goddess, gods, goddesses, or amalgamation of weird entities. The term Atheism is vague by itself; it really requires a modifier as in strong Atheist, weak Atheist and apathetic Atheist; and in order to accurately refer to a specific belief. Atheism has also been defined as anything from a lack of belief in God to a total rejection of His existence and atheism is a mounting association that is becoming more destructive, more challenging, and less broadminded of anything other than itself as is illustrated by its adherents (McGrath, 2004).
