We were some of the first monotheism people tho... Ancient tabs n shyt talking about the creator. We had other gods related to nature but nothing dark.
We basically believe that we are similar to Jesus.... and embodiment. So we say god when talking to other ones
Like these stuff about the Messiah at the Temple of Luxor.
Both dark and light existed. These spirits act on people in both good and bad ways. So to say these spirits were never dark is false. Especially when human sacrifices are thrown in the mix, which did happen in Africa. Some high priests/priestess choose to only work with the light arts, but others will work with both light and dark arts.
That Gods and Earths stuff is some 5 percenter stuff.
And similar to Jesus.... and embodiment is some Christianity stuff.
They don't use these concepts in vodou. Even the concept of mono/theism is not a concept that Africans even incorporate, cause each tribe would even worship different "spirits."
