For over two millennia, atheism has operated primarily as a position of epistemic restraint: the absence of sufficient evidence for God's existence warrants the suspension of belief. This paper argues that this framework — termed weak atheism or probabilistic atheism — has reached its structural limit. It leaves open the logical possibility of God's existence, creating a permanent gap that theistic reasoning exploits during moments of evidential uncertainty. The paper introduces evidence-based strong atheism, a new framework developed by the author that moves atheism from probabilistic suspension to evidential conclusion. Drawing on four independent lines of evidence — the thermodynamic structure of reality, the logical impossibility of creation ex nihilo, the collapse of the Kalam cosmological argument in an eternal cosmos, and the apophatic paradox internal to classical theism — the paper presents the first formally structured cluster evidence case for the ontological impossibility of a creator-God. The two-element ontological model is introduced as the framework within which each line of evidence is assessed. The paper concludes that the specific God described by major theistic traditions — omnipotent, omniscient, omnibenevolent, personal, and interventionist — is not merely unsupported by evidence but structurally incompatible with the observable organization of reality. This represents a categorical advance over all prior forms of atheism and establishes evidence-based strong atheism as the first atheism with a positive, independently grounded evidence base.
