Final answer:
African indigenous religions commonly feature polytheism, a supreme creator being, secondary deities handling daily affairs, ancestor worship, and animistic beliefs.
Step-by-step explanation:
Commonalities across African indigenous religions can often be found despite the continent's diverse cultural and religious practices. One of the core beliefs in these religions is polytheism, which is the worship of multiple deities. A supreme being is commonly featured in these religions, such as the Ngai of the Kikuyu, who is considered the creator from whom the universe originated. Yet, this supreme being was usually viewed as distant and not involved in daily human affairs. Day-to-day events instead fell under the watch of secondary deities like the Yoruba god of earth, Obatala, and the Baganda god of harvest and fertility, Makasa.
Additional common elements include ancestor worship, serving as protectors and guides, and various ceremonial practices that mark life's milestones, such as rites of passage. This ancestral veneration, along with animistic beliefs that imbue natural elements with spiritual significance, played a fundamental role in traditional African faith systems. Lastly, the way African traditional religious practices have integrated into other religions, such as Christianity, highlights the adaptability and enduring nature of these ancient belief systems.
