Which sentence in the story best indicates that it is an emergence creation story?

in the beginning all men lived together in the lowest depths, in a region of darkness and moisture; their bodies were misshapen and horrible, and they suffered great misery.

by appealing to myuingwa (a vague conception of the god of the interior) and baholinkonga (plumed serpent of enormous size, genius of water) their old men obtained a seed from which sprang a magic growth of cane.

the cane grew to miraculous height and penetrated through a crevice in the roof overhead, and mankind climbed to a higher plane. here was dim light and some vegetation. another magic cane brought them to a higher plane, with more light and vegetation, and here was the creation of the animal kingdom. singing was always the chief magic for creating anything. in like manner, they rose to the fourth stage or earth; some say by a pine tree, others say through the hollow cylinder of a great reed or rush.

this development was accompanied by singing—some say by the magic twins, the two little war gods; others say by the mockingbird. at any rate, it is important to observe that when the song ran out, no more people could get through and many had to remain behind.

however, the outlet through which man came has never been closed, and myuingwa sends through it the germs of all living things.
