Necessitarian’s argument:
P1. x creates ex nihilo, x is a se.
P2. If x is a se, x is God.
P3. If x creates ex nihilo, x is God (from P1 & P2).
P4. Human agents create ex nihilo (Flowers).
P5. Human agents are God (per impossibile).C: Human agents do not create ex nihilo (contra Flowers).P2 is obvious for anyone who holds to classical/orthodox theology. Aseity is traditionally a divine attribute of God qua uncreated. P1 is the controversial premise and I’ll employ a simple argument to its end.
P1#. If x creates ex nihilo, x is a self-sufficient cause.
P2#. If x is a self-sufficient cause, x has properties in virtue of being x.
P3#. If x has properties in virtue of being x, x exists in virtue of being x (viz. aseity).
C#: If x creates ex nihilo, x exists in virtue of being x (viz. aseity).
P3#. If x has properties in virtue of being x, x exists in virtue of being x (viz. aseity).
C#: If x creates ex nihilo, x exists in virtue of being x (viz. aseity).
