The names of other religious entities are not mentioned in ancient inscriptions. Umay arrives when a child is born and applies a drop from the Milky Way(Milk Pond) to the child's lips, thus giving it a soul and protecting the mother and child for three days. The child's smile signifies Umay's presence with them. If Umay stays away from the child for a long time, the child becomes ill. In Central Asian mythology, Umay, whose counterpart is "Ece," meaning "girl," is believed to be the goddess of the earth.
