In the African society, when a newborn child maintains its foreskin or clitoris, it is considered to not yet be its apparent sex because masculinity and femininity have the same strength. A girl who has not yet been circumcised is not a considered a woman, but both a male and female until excision is performed. If the decision was not made to be circumcised then he or she would have no interest in reproduction. The reason for circumcision and excision is to rid the child of an evil force and for them to turn to one specific sex. There is reason to believe that this practice must have started in the Egyptian society because only then is there justification in identifying the ritual causes of circumcision throughout Africa. .

In Dogon cosmogony, Amon descends from the sky on a rainbow as a symbol of rain and humidity. Throughout time some blacks have not continued with circumcision and the trend is continuing and growing throughout Black Africa. For the argument to be valid excision had to occur in Egypt as is confirmed by Strabo. Strabo says that Egyptians took care in raising their children and circumcising their children just like that of the Jews who were originally from Egypt. .
The Dogon cosmogony places an importance on the signs of the zodiac. Also the Dogon must know the star Sothis, as the Egyptian calendar was based on the rising of that star.
