In Arabic the word Khaliq means to create, not just to create but to create from nothing, without there being a previous precedence.
So God created creation, without there being anything before it.
Now, what man is doing is mixing up a few things then presenting them.
Its like a cook who has lots of ingredients and makes a meal - does he create the meal or does he simply mix the ingredients? He mixes the ingredients this is what man is doing, mixing not creating. This is how a Muslim understands it anyway.
