Description :
It has been a mystery to science about the origin of life on earth. A new theory of evolution is forcing its way into modern thinking -- that life as we know it originated in outer space. Some scientists suggested the building blocks of life might have hitched a ride on the comets and asteroids that would have routinely bombarded the Earth during its formation 4.6 billion years ago, when our planet was a lifeless and inhospitable place. In this episode, various ideas, including colonization from Mars and life-forming chemical combinations from space, are explored. It will lead the audiences to a journey to experience the richness of life.
