There are many stories of creation. The creation myths of Ancient Egypt, Norse, Greece, India, Zuni, Babylon, etc. cover far more than "a mere few pages". As "creationism" is a term most often associated with a specific interpretation of Christian faith, it sounds like you are thinking only of Biblical creation, and not the general category of creation myths. For purposes of discussion, I'll leave the Bible out entirely.
The statement was that most myths contain a kernel of truth. If that is meaningful, then shouldn't many of the creation myths also contain a kernel of truth? If so, what is the kernel in all of those creation myths?
One kernel is "people want a story to explain how they came to be." I'm actually fine with that. But then it's not really a story of oral history, but of human desires.
Another is to keep looking through the myth until something works. This seems rather haphazard in that all stories have at least something which is true. For example, Loki is the son of Fárbauti. Loki is of course either a god or jötunn, and neither of those exist, but some people are sons of other people. Is it really useful to say that this is a kernel of truth?
