“I should say we know that there are many, many other Earths out there. We're almost certain that there will be upwards of a billion Earth-like planets in our galaxy alone, so there is no lack of real estate where life might happen, but what we don't know is how likely it is given the real estate, given a wonderful pristine planet like Earth how likely is it that life will pop up inhabited? We don't know the answer to that.”

“What we want is another sample of life, which is not on our tree of life at all. All life that we've studied so far on Earth belongs to the same tree. We share genes with mushrooms and oak trees and fish and bacteria that live in volcanic vents and so on that it's all the same life descended from a common origin. What we want is a second tree of life. We want alien life, alien not necessarily in the sense of having come from space, but alien in the sense of belonging to a different tree altogether. That is what we're looking for, "life 2.0."”
