If you were to design a pantheon, how many gods or deities would you include?
The beauty of polytheism is that there is no limit on the number of deities.  The gods and goddesses can represent different forces of nature, human characteristics, ancestral principles, natural elements or animals. These can interact with each other and have children representing new concepts. Throughout the human history polytheism has been the most common form of religion and seems to be the most natural.
