Based from "Africa's Hidden History":
Credo Mutwa: The people of Rwanda, the Hutu people, as well as the Watusi people, state, and they are not the only people in Africa who state this, that their very oldest ancestors were a race of beings whom they called the Imanujela, which means “the Lords who have come”. And some tribes in West Africa, such as a Bambara people, also say the same thing. They say that they came from the sky, many, many generations ago, a race of highly advanced and fearsome creatures which looked like men, and they call them Zishwezi."
"The word Zishwezi means the dival or the glidal-creatures that can glide down from the sky or glide through water. Everybody, sir, has heard about the Dogon people in Western Africa who all say that they were given culture by the normal beings, but they are no t- the Dogon people are but ONE of many, many peoples in Africa who claim that their tribe or their king were first founded by the supernatural race of creatures that came from the sky. Are you still with me, sir?..."
"Now, sir, this story has got many versions in it. Throughout South Africa, amongst many tribes, you’ll find stories of these amazing creatures who are capable of changing from reptile to human being, and from reptile to any other animal of their choice. And these creatures, sir, do really exist. No matter where you go throughout Southern, Eastern, Western, and Central Africa, you’ll find that the description of these creatures is the same. Even amongst tribes which never, throughout their long history, had contact with each other at all. So, there ARE such creatures. Where they come from, I will never claim to know, sir."
"But they are associated with certain stars in the sky, and one of these stars is a large group of stars which is part of the Milky Way, which our people call Ingiyab, which means “The Great Serpent”. And there is a red star, a redish star, near the tip of this huge rim of stars which our people call IsoneNkanyamba. Now, this star called IsoneNkanyamba, I managed to find its English name. It is the star called Alpha Centauri, in English."
"Now, this, sir, is something that is worth investigating. Why is it that well over 500 tribes in parts of Africa which I’ve visited in the last 40 or 50 years or so, all of them describe similar creatures? It is said that these creatures feed on us human beings; that they, at one time, challenged God Himself to war, because they wanted full control of the universe."
"And God fought a terrible battle against them and He defeated them, injured them, and forced them to hide in cities underground. They hide in deep cavities underground, because they are always feeling cold. In these cavities, we are told, there are huge fires which are kept going by slaves, human, zombie-like slaves. And, it is further said that these Zuswazi, these Imbulu, or whatever you choose to call them, are not capable of eating solid food."
"They either eat human blood, or they eat that power, the energy that is generated when human beings, on the surface of the Earth, are fighting and killing each other in large numbers. I met people who have fled from the early Masaki in Rwanda, from years ago, and these people were horrified by what was happening in their country. They said that the slaughter of the Hutus by the Watusi, and the Watusi by the Hutus, is actually feeding the Imanujela, monsters. Because the Imanujela like to inhale the energy that is generated by masses of people being terrified or being killed by other people. Are you still with me, sir?"
So, when Credo had stated on God battling the Chitauri, this is based on the story of "Red Horn" who was sent by God to battle the monsters, Giants and other Alien entities. This information was already established, but it's good to know who how the Chitauri and the Nommo connect to each other. Even Credo Mutwa had stated in "The Reptilian Agenda" on how the constellation of Orion and how God had sent a warrior to battle the dragon gods and other nasty Aliens. This "warrior" is none other than Azazil, who is Iblis, Red Horn, Michael, and the God of fire as Agni.
