@hingehead,
The Dogon people of West Africa had a complex and vividly described religious tradition which had no gods, and cold be described as animist. Animistic religions often do not involve gods--one of the most common animist traditions is to ascribe to the sun the attribute of life-giving, which has lead European anthropologists to describe the sun as their god. That, however, is very likely a projection of the theism of the anthropologists' native culture to the animism of the people they are studying.
The Dogon are also interesting because they appear to have had very advanced astronomical knowledge, and the Frenchman who studied them from 1931 onward, for about 15 years, claimed they had told him that the twin "deities" (once gain, probably a cultural artifact of the Frenchman, and not necessarily the attitude of the Dogon themselves) had come from the star Sirius. It is significant, though, that the Frenchman who studies them for about 15 years from 1941 to 1956 does not mention these twins as deities, and his Dogon informant had told him about their religious beliefs in detail throughout that time period, and had told him that his father and grandfather had instructed him in Dogon traditional belief for 20 years or more. The problem one always has when anthropologists describe such cultures, and even more so when explorers or representatives of colonial authorities describe the culture is the problem of projection. Do the animists believe in gods, or is that just how the Europeans interpret the beliefs which are described to them?
