Furthermore, a lack of evidence for gods does not mean that scientifically there are no gods. The only way for things to be disproven definitely is through mathematical proof. Because this cannot be shown in a mathematical proof (there is no mathematical way to represent godhood) the concept of a god cannot be definitely disproven in scientific approaches. Otherwise the most scientific claim is merely "we cannot find any evidence for <concept>" with the logical step being that therefore <concept> doesn't exist or has a low statistical chance of happening- but this is a cognitively easy conclusion and not what science is actually doing.
Science and the scientific method is actually extremely limited when dealing with the concept of dieties. It can only say that, given claim X, experiment(s) were run that did not verify X. After enough experiments are run, they are evidence X is not true. But none of these are absolutes, and claiming a mountain of evidence is a definitive scientific proof is itself unscientific.
