You have provided no evidence that any of the Founding Fathers were Creationists.
You think that the Founders who were Christians did not believe that God created the universe? Even deists believed that God created the universe and then left it to run on it's own.
I think it is sufficient to show that the Founders were Christians to prove that they believed in creation, and t. A creationist is someone who believes in creation.
