Well, simpler than that.
No matter what the field of biology may hold, our constitution is quite clear: the United States is a secular government that is expressly forbidden in upholding religious tests or endorsing religions.
Creation dogmas are found in a variety of religions and to teach one or more of them in a setting funded by public monies has been found by our court system to be incompatible with our constitutional government.
