Creation is neither fun nor real, if the creatures are not independent. God has created surprises for Himself. His knowledge extends to great depths to know approximately what they will do, but in general the humans surprise God with horrors, while the angels surprise God with delights. The angels are not a problem for God or for one another. They investigate the ten thousand possible routes of goodness, while humans fall predictably into the one choice of evil as fully governed by their local sense experience.
Craig speaks of his own mind, presuming I think favorably, that he can speak boldly and God will accede there is an echo. To know about the creatures is to know their tendencies. The exact tendencies on this exact Earth, are repetitions of former situations that Craig may remember. If you have looked many times to know, you don’t need to look again to know, and the properties of the human plane are lamentably predictable. Importantly too, Craig may acknowledge the world God sees is the world that God builds. It won’t be the same if He fails to act, but also it won’t be the same if angels fail.
