Give me a brief summary about the origin of humanity from the Kikuyu?

According to Kikuyu mythology, humanity originated from a single couple, Gikuyu and Mumbi, who were created by Ngai, the Supreme God. Gikuyu and Mumbi were placed in the Garden of Eden, known as Mukurwe wa Nyagathanga, where they lived in harmony with nature and animals. They had nine daughters, who went on to marry and populate the earth with their descendants. The Kikuyu believe that they are direct descendants of Gikuyu and Mumbi, and that their ancestors continue to watch over and guide them.
