An Abductive Cosmological Argument

Let us define God as the non-natural sufficient explanation of nature.  If so, I think the following abductive argument presents a plausible reason to believe in God.

P1: If God is not the best explanation for nature, i.e. the whole of natural reality, then either nature is self-explanatory, or we ought to think nature is brute, i.e. it has no explanation.

P2: If nature is self-explanatory, then the quiddity of nature, i.e. what nature is, includes its facticity, i.e. that nature is.

P3: It is not the case that the quiddity of nature includes its facticity, i.e. the existence of nature is not an analytic truth.

P4: If we ought to think something, x, is brute, then then all things are among those which have been eliminated as possible explanations for x.

P5: God is not among that which has been eliminated as a possible explanation for nature.

P6: If God is the best explanation for nature, then it is probable that God exists.

C: It is probable that God exists.

The deduction is as follows:

C1: It is not the case that nature is self-explanatory [from P2 and P3 by Modus Tollens].

C2: If we ought to think nature is brute, then all things are among those which have been eliminated as possible explanations of nature [from P4 by Universal Instantiation].

C3: Some things are not among those which have been eliminated as possible explanations for nature [from P5 by Existential Generalization].

C4: Not all things are among those which have been eliminated as possible explanations of nature [from C3 by Contradiction].

C5: It is not the case that we ought to think nature is brute [from C2 and C4 by Modus Tollens].

C6: It is not the case that nature is self-explanatory, and it is not the case that we ought to think nature is brute [from C1 and C5 by Conjunction].

C7: It is not the case that either nature is self-explanatory or we ought to think nature is brute [from C6 by DeMorgan’s Theorem].

C8: It is not the case that God is not the best explanation for nature [from P1 and C7 by Modus Tollens].

C9: God is the best explanation for nature [from C8 by Double Negation].

C10: It is probable that God exists [from P6 and C9 by Modus Ponens].
