Even if theism is a failure, it's still superior to atheism

[Angrboda]

And your definition is plainly ridiculous. Absence of evidence isn't evidence of absence. That something is undetectable just means we can't detect it, and that empirical observation isn't enough to justify the assertion that it exists.

If something is undetectable, even in principle, then it is indistinguishable from non-existent.  We can dismiss its existence without further ado.

Oh geez, don't do that! Now he'll just talk some more.
