Life on earth coming from another celestial body is also a well accepted concept among some sections of the scientific community. They believe that life did not originate on earth rather came from some celestial body in the form of microspores. Lord Kelvin, Von Holmholtz, etc. proposed this concept in the nineteenth century. This concept was supported with new facts by Fred Hoyle, Vikramsinghe, Jayantvishnu Narlikar, etc. in the twentieth century. But compared to Primordial Soup Theory, this concept could not gain much acceptance.
