A dominant question what is life & how did it arise ? Only possible on Earth ? Life is the aspect of existence that processes, acts, reacts, evaluates, and evolves through growth (reproduction and metabolism) as a define, physical observation. The crucial difference between life and non-life (or non-living things) is that life uses energy for physical and conscious development. On above manner, Eco Astronomy concepts fundamentally developed, base on harbor life which describes the origin, evolution and existence of life in the universe, Therefore this disciplines representing as a kin subject to interpreting comparative model for any harbor life organism. Resulting the gradually evolution of physical life, evaluated neurological impactation & thinking patterns specifically applicable, human like being. Modern humans have an RBS of roughly 2%, and this value is neither the smallest nor largest in the animal kingdom or even in the primate order. It is also possible, when body and brain sizes are known, to calculate a statistic called the
“ Encephalization quo- ient EQ . An EQs value depends on the database used to make the calculation (Homocentric equation). Comparative analysis of EQ & brain morphological indicators, has been concluded the stimulation ration of active brain cell & speciation for harbor life which exist.
