Civilization, or specifically agricultUre, appears to have started in Mesopotamia. And among the earliest god that man recognized there have been the snake-gods. Now a Mesoptamian snake-god was Ningizzids. Frankfort (1934;11) writes that "Nimurta and Ningizzida are epithets of the same deity, as warrior and hunter. One as earth god, the other as god of fertility. Moreover, (p.13) "Prof. Langdon says : Ningizzida as serpent-god. And his name is sometimes Shahan=F ire. His other name is Sherah= Grain vegetation, indicating connection with earth's fertility. This aspect of Ningizzida as Lord of Vegetation is depicted with a sprouting plant held in his hand. Thus we have in Ningizzida a god of hunters with two phases, Shahan as Fire, and Sherah as Lord of vegetation. Transporting Shahan to Rigveda we have Agni and transporting Sherah, the Lord of vegetation, we clearly have Soma. These two aspects of Ningizzida would correspond to Ragozin assigning priority to Agni and Soma among the deities. of Rigveda. But we have explained that Fire is the Son-of Water so that the two primary powers become Water and Soma. Then Soma and Water with Fire as its issue equal Ningizzida. Earlier we have explained that Soma is an energizer, it is also an aphrodisiac and as such it is a "Durosha, as an ephithet of the lowers" drink. Finally it has been symbolized as a youth to whom damsels bow down. Now as hunters the nomads like to see animals multiply so that there was no scarcity of game. Accordingly, to pray to Soma would be to pray to a god of fertility. Thus recognizing his two main characteristics, as Lord of vegetation and as Promoter of reproductivity when Sonna=Ningizzida. Now once there is the recognition of power of reproductivity this when abstracted becomes creativity. In fact to the primitive thinker Re product ion= Creat ion. Thus Soma, to whom the power of reproductivity has been assigned, functioned as proto-Akasha when Akasha=Brahma=Creator. Only now can we construct the proto-cosmology of Rigveda. By cosmology we understand the structure of the universe with the irreducible basic powers, be they qualities or elements. It presents the universe' as a dynamic whole. The qualities recognized here have been Heat, Humidity and now Reproductivity. Heat was the quality of Fire, Humidity of water and Reproductivity of Soma. Soma thus functioned as proto-Akasha, the creative powers. Then as father and son are one, when we speak of Agni and water as its son, the same identity is also implied thereby. Hence Agni and Soma virtually mean Fire, Water and Soma as the three elements of Proto-cosmology and as qualities Heat + Humidity + Creativity = Cosmogony.
