djzpt:If you are in this discussion regarding Evolution versus Creationism, and then use the term God, I fail to see how one is to misunderstand which religious belief you are referring to.
Considering he said he was not a Christian this shouldn't have been that hard for you. Pretty much by definition he wasn't replying to the Christian God.
Being a Christian has at least one specific belief that all must hold (with due deference to some unitarians who still identify that way)--that Jesus Christ is the Son of God and died for one's sins. In saying that one believes in God, but is not a Christian, one is simply saying they believe in a Supreme Being, but not the specific beliefs of Christianity and in his clarification--other organized religions.
I'm rather confused by your position here given Percy was clear. Additionally, from time to time creationists do come in who don't argue YEC Christian creationism, but something akin to Hindu creationism. Michael Cremo was just in St. Louis recently, though I missed his talks.
