This is a creation myth from a Native American oral tradition — specifically from the Kumeyaay (Diegueño) people of southern California — recorded and transcribed into written English, likely in the late 19th or early 20th century. The narrative follows the creator deity Tu-chai-pai and his brother Yo-ko-mat-is as they construct the world through ritual speech, tobacco, and physical labor: raising the sky, establishing the cardinal directions, shaping terrain and water sources, and fashioning humans from mud. A distinctive feature is the collaborative but hierarchical dynamic between the two figures — Tu-chai-pai already knows what must be done but questions his brother, drawing out the brother's participation rather than acting alone. The text makes notably practical claims about why the world is structured as it is: forests exist so people won't freeze, small water sources were placed specifically for human travelers, and the moon's phases serve as a communal signal for ritual foot races. The creation of humans is rendered with candid asymmetry — men are made well, women imperfectly and with great effort — and a social hierarchy is embedded in the sequence of creation, with Indians made before Mexicans. The myth closes on a contemplative note, with the Maker withdrawing from active creation into prolonged thought, suggesting ongoing cosmic attention rather than abandonment.
