I think she she misspoke. To a Christian, God comes before everything else. "In the beginning, God created Heaven and the Earth."
Then the Greeks, then the Romans and then Jesus was born.
As for the fact that she doesn't believe in evolution, lots of Christians don't. (I believe that there's got to be some sort of combination as the two, but that's just me.)
And yes as Caitlin stated, as Christian, we do belive that God has ALWAYS been around. Because in the beginning was God. He created ALL things. So Yes, he would have been around before the Greeks, Epicuris, etc....I will stop here because I know they do allow religious discussion on the boards.
