Creation science or not?

Does all Creation science claim that? Or only YEC.
Is there some kind of rule that says in order to be a Creation scientists you must be a a literal YEC?

In accomplishing the goal of separating parts of polybaramins, partitioning apobaramins, building monobaramins and characterizing holobaramins, a taxonomist needs guidelines for deciding what belongs to a particular monobaraminic branch. These standards will vary depending upon the groups being considered, but general guidelines which have been utilized include:1. Scripture claims (used in baraminology but not in discontinuity systematics). This has priority over all other considerations. For example humans are a separate holobaramin because they separately were created (Genesis 1 and 2). However, even as explained by Wise in his 1990 oral presentation, there is not much relevant taxonomic information in the Bible. Also, ReMine’s discontinuity systematics, because it is a neutral scientific enterprise, does not include the Bible as a source of taxonomic information.

Doesn't it at least start with a theory? The theory that God exists?

We believe that the theory of evolution is a foundational scientific truth, one that has stood up to rigorous scrutiny and upon which much of human knowledge and achievement rests. To reject this truth or to treat it as “one theory among others” is to deliberately embrace scientific ignorance and transmit such ignorance to our children. We believe that among God’s good gifts are human minds capable of critical thought and that the failure to fully employ this gift is a rejection of the will of our Creator. To argue that God’s loving plan of salvation for humanity precludes the full employment of the God-given faculty of reason is to attempt to limit God, an act of hubris.

Ok maybe I was wrong about Columbus not thinking the earth wasnt round (circle as it says in the bible) but there were many others who did.
