The point is, belief in God does not require religious faith but belief God doesn't exist is based on no evidence so it must require faith.
That's false.
Beliefs based on faith: require no evidence (and thus can also be made in spite of evidence to the contrary!)
Beliefs based on reason: require evidence/observation.
There by definition cannot be evidence in reality, of the imaginary.
There are plenty of definitions of god that defined God as imaginary.
I can do it right now.
Mog, a god, is an imaginary entity I just made up, that can bend space and time and has eyes made out of black holes.
According to you, it requires faith to believe this is imaginary. That's absurd. It's imaginary *by definition*.
Remember, the claim "gods is imaginary" is not a claim about reality, it's a claim about not-reality. This is a confusing point in the English language, no doubt, but there it is.
Either we're discussing reality, or not reality.
A claim about the not-real, is a claim about not-reality.
A claim about the real, is a claim about reality.
To say "there is no such thing as gods", is not an examination of the entire universe uncovering every atom, and declaring "no gods were found". It's a claim, in most cases, that the concept of god is imaginary...by definition.
The classic Christian god is defined as supernatural...aka...outside of nature.
That by definition, means outside of reality...not real. It's imaginary, by definition. Logic/reason...no faith required.
