I don’t consider that I’ve “proved through logical reasoning that God as Christians know him does not exist.”
I haven’t read C.S. Lewis’s “proof,” but there are dozens of such “proofs,” which all work fine—provided that you accept the premises on which the proof is based. As far as I’m concerned, neither the existence nor the nonexistence of God can be established (and writing a “proof” doesn’t accomplish that).
