Actually...let me restate my assertion.
NASA and the Science community has said that Life on earth needed a push, or a jump start. They do not know what, but they agree upon that fact. Based on that.....anything is possible.
I think you're talking about Panspermia...it's an idea that life here could have been seeded by some extraterrestrial source. But that could be as simple as comets distributing organic compounds or even simple microbes into the early Earth atmosphere. It's not "divine," however, more an introduction of organic compounds from interstellar space.
And it's not something the scientific community and NASA have said as a whole. It's an idea...barely a hypothesis, and certainly nowhere near a theory.
