In this paper, the creators, the helpers of the creator, the causes of creation, the process of creation, and the purpose of creation of earth origin myth of the evenki and even, were examined. The evenki and evenian myths have similar motifs, structures, and characters, but there are various versions. According to Levi Straths, the repetition of myths with the same structure, resulting in different versions, is due to the characteristics of the myth itself to more clearly represent the structure of the myth(Im BongGil 2005, 63). The evenki's earth origin myth is divided into a “extended earth” type's myth and “earth support” type's myth. The former, which the shape of the earth grows as the mud brought by the creator's helper grows under water, and after the creation of the earth, while the other a that the creator's helper supports under the earth so that the earth does not sink after a single collapse process. In the even's myth, only the earth expansion type was found, but the earth support type was not found. In the evenki and evenian earth origin myth, abishai appears as the main helper of the creator. Abishai symbolizes water, earth, sky/ upper, middle, and summer due to its ability to move freely between water, earth, and sky, and after accepting shamanism, it became a mediator in the loop of celestial world middle-earth underground. ⇔ ⇔ For the evenki and the even, the abundance and productivity of the earth is desperately needed to maintain basic life. Because abishai possesses all three of these elements, it was bound to be worshiped by the evenki and even. The purpose of the creation of the earth in the evenki and evenian myth is the completion of the celestial world, middle-earth, and underground three-tiered worlds and the completion of the universe order. Their earth origin myth was initially self-generating, and was subsequently influenced by adjacent asians, altai mongols and turks, and after entering russia's sphere of influence, it is presumed to have been influenced by russian orthodoxy.
