If you're talking about young earth creationism it isn't even close. If you just mean that God initiated evolution millions of years ago, the two are compatible but it's still not exactly science. Evolution can be and has been observed. God and creation can't be. There is tangible evidence that evolution has happened. There isn't for creation. It's 100% hypothetical at best. It'd fit into a class that's actually about religion and philosophy and stuff, but saying it should be taught as science is like saying Pythagoras should be taught in English Lit. Two completely different fields.
