His view is that what’s going on here is that all of creation happened to prepare the land for man. In verse 1, “In the beginning he made the heavens and the earth,” he makes everything. And then you go day by day and he’s preparing the land. He’s not bringing new things into existence; he’s preparing the land and causing things to grow and separating out water and earth. And then, when it’s all set and prepared, he creates and puts man there.
That the earth is billions of years old if it wants to be—whatever science says it is, it is—but man is young, and he was good and he sinned. He was a real historical person, because Romans 5 says so, and so does the rest of the Bible.
