This study aims to examine the diverging aspects of the God of creation's role in Creation myth, in respect to the analysis of the transmitting aspects of the creating mankind, sun-moon and heaven-earth. The first noticeable result indicates that the highest God of creation were diverged into the God of creation in higher grade, God of creation in lower grade and the mankind created by the highest God of creation. Because various versions of Creation myth are singly transmitted, on the other hand organically correlated to each other, it can be assumed that a man and woman creating mankind, sun and moon in Creation myths has referance to the mankind created by the highest God of creation, putting various versions of Creation myth together and from diachronic point of view. The second noticeable result indicated that the three Gods system is revealed in Creation myths of Korea, Manch, Mongol. Then I think that it was ascertained that a ranks of the God could be commonly established in three nations. Extending the point of an argument, it can be assumed that the context of various versions of Creation myth is established from diachronic point of view in three nations.
