Chapter 25: Schemes > Section 25.13: Points of schemes

Lemma 25.13.3. Let $X$ be a scheme. Points of $X$ correspond bijectively to equivalence classes of morphisms from spectra of fields into $X$. Moreover, each equivalence class contains a (unique up to unique isomorphism) smallest element $\mathop{\rm Spec}(\kappa(x)) \to X$.

Proof.Follows from the discussion above. $\square$
