We present a case for Cosmological Nucleosynthesis in an FRW universe in which the scale factor expands linearly with time: a(t) ∼ t. It is demonstrated that adequate amount of 4He requires a baryon density that saturates mass bounds from galactic clusters. There is a collataral metallicity production that is quite close to the lowest metallicity observed in metal poor Pop II stars and clouds. On the other hand, sites for incipient low metallicity (Pop II) starformation can support environments conducive to Deuterium production up to levels observed in the universe. A profile of a revised ``Standard Cosmology'' is outlined.
