Creation Narrative

How should one explain the marks of similarity between the biblical narrative and the creation sagas of pagan peoples? This similarity seems to demand that the creation story was known before Moses and that traces of it were preserved by pagans. Of course, if the narrative came to Moses completely or in part by tradition, this in no way detracts from the inspiration by which he was enabled to record it fully and infallibly.
