The Invalidity of Atheism
Agreed, there's also a bias for being or existing things at least epistemologically.
If we deny quantum mechanics then we epistemologically never deny/negate physics entirely (we could be extreme general relativists or string theorists) however if we assert quantum mechanics, then that entails mechanics (at least epistemologically).
If atheism is defined as the negation of theism then I'm not sure how one ever gets to that position even given infinite negations of physical theories.
Now physics can be shown to be an issue by attacking the premise of it (that the material universe is fundamentally matter and energy) but this doesn't seem to imply that physics has no validity or doesn't exist in this world (can't be talked about) or that we have the means to justify that we have exhaustive means to show it doesn't exist.
I think atheism ends up throwing the baby out with the bathwater and theism, and even atheism, should be assumed that they are real but in terms of what they are like social constructs etc.
