The atheist believes it is purely rational to believe there is/are no god/s, they believe that absence of evidence is indeed not just evidence of absence, but sufficient proof of absence. They believe that they know all {A} such that there is no possible {A} that is not {B}.
Who, exactly, is '
the atheist'? At the risk of repeating what has been said many times, all atheism requires is a lack of belief in God. The above is clearly a strawman of the position advocated by most (or at least a sizeable proportion of) atheists on this forum.
I certainly do not believe I know all {A}; and yet - like everybody else - I do not require a rigorous proof before I will believe in the existence of thelaptop I'm typing on; nor before I will say I do not believe in the evil monkey in my closet.
To return to your Loch Ness analogy, and what I assume you were trying to put across, then no - of course demonstrating the God of the Torah to be a myth would not demonstrate all concepts of deity to be a myth. No matter how many gods we dismissed, we haven't dismissed all possible concepts of god. But this is simply an argument for agnosticism, and doesn't really tell us anything of value. We all know that we cannot describe the real world with the same certainty we can prove a mathematical theorem, but so what? You can't prove you're not a brain in a jar, either. What support does all this offer for the idea of a deity?
In summary, to qualify as an atheist, one has to lack belief in God. One does not need to be unshakeably certain that no concept anyone, anywhere described as God could or does exist.
