If the Chinese had colonized your ancestors like the Europeans and Arabs did, most of you would have been Buddhists and claim it is the best religion and think Budda is the creator.
In this day and age, it is downright folly to think that Yoruba religion is evil. In Yoruba religion, there is one God, called Olodumare or Olorun, who is responsible for the creation and the upkeep of what He made. He has deities who serve to perform His work and act as links between mankind and Himself. These holy messengers are equivalent to angels and are called Orisa.
In Yoruba, you must believe in Orisa if you are to reach God-consciousness. Yoruba angels never fell from God’s grace.
