Every terran living being comes from a common ancestor and life originated only once in 4.6 bi years. So it is unlikely to occur outside Earth, right?
I've heard that every terran living being comes from a common ancestor and life originated only once in 4.6 billion years. So it is unlikely to occur outside Earth, right?
That's correct. While it's technically possible for life to have originated multiple times, based on what we've observed on Earth, it's likely that life is a rare and precious commodity in the universe.
