Nainuema is the creator of the Uitoto cosmogony recorded by Konrad Theodor Preuss, whose account is among the most celebrated instances of creation ex nihilo in the ethnographic record. The Father, addressed as Moma, calls himself Nainuema, 'he who is or possesses what is not present.' In the beginning there was only an illusion or phantasm; through dream (nɨkaɨ) the Father seized this appearance, bound it with a gluey dream-thread, and stamped it flat until it became the solid earth on which he could stand. Sources differ on whether Nainuema is a separate creator or an aspect of the supreme Father also known as Juziñamui, and the tradition treats the two names as facets of one generative power.
