How do the theory of evolution and theory of creationism fit together?

I believe God got the ball rolling. What i don't like about literal creationism is that it implies that God stopped creating after 7 days. I think he kept creating, and is still creating today. Evolution did happen, but God was behind the whole thing. Well let me illustrate a bit. When a sculptor uses clay, the clay doesn't take it's completed form immediately. It takes time. That's how I see that God created the world, he took his time. And why not? It's his own creation, not like he had a deadline or anything....
