Atheist does to require a belief, the belief that deities don't exist.
Since that is NOT knowledge, it's belief, opinion, faith, trust, confidence, persuasion, credence, whatever you want to call it, it's not a fact that deities don't exist.
Since a FACT is......"A piece of information used as EVIDENCE" ( your lest favorite word) And since there is no EVIDENCE for deities, it become a FACT that deities do not exist.
You'd do well to try and really understand the following. I do understand that no amount of logic or reason can penetrate the damage that religion has done to your thought process, but give it a try.
"When considering any matter of philosophy, ask yourself ONLY what are the FACTS and what is the TRUTH that these FACTS bear out. NEVER let yourself be diverted either by what you WISH to believe, or by what you THINK would have been socially acceptable to believe, but look ONLY and SOLELY at what are the FACTS." Bertrand Russell
