In the study of “myth”, scholars have long debated its conceptual boundaries and interpretative frameworks. Creation myths, as sacred narratives that elucidate cosmogony and anthropogenesis, offer unique insights into humanity’s primordial worldview. This thesis conducts an intercultural comparative analysis of The Welkin War—a foundational epic in Manchu oral tradition—and Ancient Near Eastern creation narratives, focusing on their cosmogonic frameworks, divine hierarchies, and ecological philosophies. By juxtaposing motifs such as primordial chaos, divine conflict, and anthropomorphic agency, the study reveals divergent mythological logics shaped by distinct geopolitical and cultural ecologies. Specifically, it highlights how the matrilineal cosmology of the Manchu text contrasts with the androcentric theogony of Mesopotamian myths, while both manifest profound reverence for natural forces. Methodologically, this research integrates structuralist analysis with ethnographic contextualization to illuminate the interplay between mythopoeic imagination and socio-cultural evolution.
