"Creationism does not do this. Instead it denies that humans have a place in the development of the living things on this planet,"

You're right. Evolution does not "contradict" the existence of God(s). Here's a critical difference between the real scientists and the pretenders: The real scientists are trying to find out while the pretenders are trying to justify what they think they already know.

The real scientists don't take loyalty oaths to defend their preconceived intellectual biases. They tend to actually do their homework before coming to their conclusions - and not spend their careers trying to justify what they want to believe is true. Real scientists don't credulously accept random religious screeds and then cavil to ignore the actual evidence.
