english: He won't call himself an atheist because it's, in principle, impossible to prove a negative, but "agnostic" on its own might suggest that God's existence was therefore on equal terms of likelihood as his non-existence.
non_english: Nenazýva sám seba ateistom pretože je v princípe nemožné dokázať negatívne tvrdenie, ale pojem agnostik ako taký naznačuje, že existencia Boha je rovnako pravdepodobná ako jeho neexistencia.
