Atheism has nothing to do with the scientific method. There were philosophical / logical arguments for atheism before science even came along. Some of the great atheist philosophers lived thousands of years ago. Science, and the scientific method, is much more recent.
Nor does science somehow prove atheism, or that atheism somehow "relies" on science. Atheism is the disbelief in gods. I don't see how the existence of gods is a scientific question at all. Science deals with the natural, not the supernatural. It deals with the observable and testable, not the unobservable and untestable.
So yeah, you are very confused if you think atheism is anything but a simple stance on belief in gods.
