Could there be another theory of how life got started on earth? Perhaps life came here on a comet. This theory has never been discounted in the scientific community, but now there may be a real possibility that the building blocks of life came to earth on some kind of vehicle, most likely a comet. Also another nation joins space exploration. South Korea is attempting to get a launch vehicle off the ground in the coming weeks making it the 10th nation to launch a satellite into space.
