"Look at the solar system, and look at the Earth. On Earth, there are many intelligent species, but only one has achieved technology. Right here in the journey of our own solar system, there is a very, very powerful message that says here's how we should look for alien life, small and big. So yeah, microbes are talking and we are listening, and they are taking us, one planet at a time and one moon at a time, towards their big brothers out there. And they are telling us about diversity, they are telling us about abundance of life, and they are telling us how this life has survived thus far to reach civilization, intelligence, technology and, indeed, philosophy."
