Then you should start by actually getting your facts straight.
Atheism is NOT a "faith" proposition. It is the denial of "faith" as a valid position.
Literally a-theism is "without theism". More accurately it is "without belief".
It is most definitely NOT a substitution of one belief for another.
Let me try to put it in terms you can understand --
You claim that there is a god. As an atheist, I simply doubt YOUR claim made without evidence.
That's really no different than what you do with anybody else's "god" claim. When a Hindu person claims that Shiva, Vishnu, and Brahma exist, you doubt their claim and ask for evidence ... real, independently verifiable evidence.
"Atheist" comes from the greek root "atheos", meaning no god, or without god. Atheism is the belief that no god exists.
Simply doubting the existence of god, or claims to that effect, is "agnosticism".
If you are going to claim to be an atheist, perhaps you should first learn what it is.
