What religious belief did the Bantu have that was similar to Christianity and Islam?

The Bantu people traditionally believed in a supreme creator god, along with a pantheon of lesser spirits and ancestors who played a significant role in their spiritual life. This belief in a higher power and the veneration of ancestors parallels the monotheistic aspects of Christianity and Islam, which also emphasize a relationship with a singular God and the importance of community and moral conduct. Additionally, these religions share concepts of guidance and protection through spiritual intermediaries, reflecting a common understanding of the divine's role in human affairs.
