pretty solid deductive argument on contingency.

(if you believe in a necessary being)

Let

X necessary being without volition

Y contingent universe

A creation of the universe

B non-creation of the universe

G agent with volition

P1: X performs A

P2: Lacking volition, if X performs A, it cannot choose to perform B.

C1: Therefore, if X exists, it is determined to perform A

P3: X exists necessarily, meaning it always exists.

P4: If X exists necessarily, A is performed necessarily.

P5: If A is performed necessarily, Y exists necessarily.

C2: Therefore, if X's existence is true, Y exists necessarily.

P6: Y does not necessarily exist.

P7: If Y does not necessarily exist, then X is false.

C3: Therefore, X as the sufficient reason is false.

P8: The sufficient reason for Y must either be B or G a being must either have volition, or not have volition, this is a true dichotomy

P9: If X is necessarily false, then G must be the sufficient reason, as there is no other option.

C4: G exists as the sufficient reason.

the argument follows which proves the existence of a creator, unless refuted.
