First One Father, Then Another

Regeneration means becoming the seed of another—ultimately, having one family tree and then acquiring another. My father used to be Adam and now he is the second Adam. My father used to be the devil and now he is Abraham. A creature being summoned into being ex nihilo is being created. We might say he is being born. We would never say that he was being reborn. Rebirth entails having been in existence already, with another father.
