In the Vedas, the belief {that all life began in the “Waters”} appears in the form of an old popular theory, for which are substituted the successively more philosophical concepts of Space Cosmology, of a belief in the origin of the world in Non-being, in an origin of the world from Being, and finally in the conception of Brahman (the Absolute) as world-ground. The Water Cosmology, it is true, persists side by side with, and linked with these deeper views, even in post-Vedic literature; but it is typically not a creation of the Vedas and seems to belong to an even older stratum of ideas than that which is developed in the Vedas.
