explanation regarding the origin of Universe in the controversial 'Big Bang' theory for evolution of the Universe (Arp et al. 1990), nor does it provide any satisfactory explanation regarding the origin of life despite considerable advancements in the fields of astrobiology, astrophysics, and molecular biology in recent years.

Abstract. Studies of the Earth's earliest biosphere have suggested a close coupling between the evolution of early life forms and the physical and chemical evolution of the planetary surface. From a biological perspective there were many similarities between early Earth and early Mars. This has led to the idea that an origin
