Agnosticism
 People often have difficulty telling agnosticism and atheism apart. Atheists do not believe in the existence of deities, and some say that they are sure that no deity exists. They state that there is neither enough evidence nor a strong enough argument to believe any gods exist, and so they reject belief that any exist. While agnostics think we cannot 'know for sure' whether any deities exist, some agnostics do 'believe' at least one deity exists. Some agnostics just cannot themselves decide whether to believe any deities exist or not.
