Abstract
We construct a sequence of transitive finite sets A n, n∈ω, such that, putting A = U n∈ω A n, A is transitive of rank ω (without urelements) and, for every sentence Φ in the language of set theory, A {models}φ if and only if A n {models}φ, for all but finitely many n's. This implies the claim of the title.
