Nope. That's not how it works.Because you have confidence, faith, trust in your opinion that there is no god.
It's commonly said that the position of not having a belief in god(s), "atheism", is just as tenuous a position as a belief in god(s),"theism". The notion being atheism requires a faith of some sort to not have a belief in whatever deity is being discussed.
Essentially saying an atheist has to maintain a counter belief in Vishnu, Brahma,Yahweh, Allah( the un-same 'god"), Jaguar gods, Tree gods etc...at all times.
By that reasoning, a theist who believes in one god, then by extension has to maintain a belief in the non belief of all other gods...I don't think that's the case.I think if it's considered in that light, then most would see why being atheist doesn't require a faith in not having a belief.
Atheism isn't specific towards any particular god(s). It isn't a belief.
Theists will argue, no matter the god they believe in, that an atheist somehow maintains a belief that is specific to each individual's god of not existing.
I'd add it's said the atheist and agnostic, wouldn't exist if not for the beliefs of theist's, this is correct.
Anyway, the following are some creatures, beings, gods, etc..that required belief, and do not require a belief to not believe in...from various cultures and regions: Minotaur, Re'em, Kholomodumo, Apollo, Dead Sea Apes, Centaur, Trenti, Hel, Haetae,?kubi, Golem, Polong...
The following are from the U.K ..Lubber fiend, Joint-eater, Joan the Wad,(love you guys), and finally for a contemporary example from the U.S, although the Catholic church I'm sure shudders at the name.........(drumroll& cymbal clash)
The nefarious Pope Lick Monster.
There are numerous others, and I assert that in each instance the people who said or say "no, these creatures/beings are not real" were accused of having a faith in a belief that they didn't exist. In retrospect, it's obvious they didn't(exist), and by the same token you can't say that by lacking a belief in something that is found to be real, is a form of faith in "un-belief" either. As an example: the Minotaur is found, archaeological skeletal evidence.That would only support the people who believed in them years ago(who are dead and gained nothing by the faith in the belief).
Yet , god belief is seen as a separate issue, and is in reality no more deserving of maintaining a belief in by faith, than anything else that people have believed in (mythical creatures , monsters etc...) using faith to support, past or present.
I should add that if any of those previous , current or future beings/creatures/"superna tural things" that people have believed in or yet to believe in are found to be actual...they will not require one bit of belief, or faith to support a belief, to understand that they are in fact real.
If that were to happen, I'd have no problem changing my lack of a belief in any of them to a position of knowing they are real, btw.
No faith required.
But we both know what you call faith and how you apply that in your deity belief - and how you apply that to atheists - isn't the same.This is not a fact, this is your belief. And you have complete faith in that belief.
