Satanism is a complex and diverse set of beliefs, and it's important to avoid generalizations. Here's a breakdown to address the question:
* Satanism is not the opposite of believing in God: Some forms of Satanism are atheistic and do not believe in God or Satan as literal beings.
* Theistic Satanism: Other forms of Satanism are theistic and worship or revere Satan as a deity.
* Satanism is not devil worship: Even in theistic forms, Satan is not necessarily seen as an evil figure, but rather as a symbol of rebellion, individualism, and self-empowerment.
In conclusion, believing in God and being a Satanist are mutually exclusive. Satanism is an alternative belief system.
