All arguments for and against the existence of God are inherently unfalsifiable, but that doesn't mean atheism is inherently more logical than theism.
I'm guessing you're one of those people who thinks atheism means a belief in the absence of a god, rather than its actual meaning, which is an absence of a belief in a god.
"Writers disagree on how best to define and classify atheism, contesting what supernatural entities are considered gods, whether atheism is a philosophical position or merely the absence of one, and whether it requires a conscious, explicit rejection; however, the norm is to define atheism in terms of an explicit stance against theism."
