"What is [life] it? Would we even recognize it. What I imagine we would find would be cell-like things. Not a million miles away from bacteria, using , probably in water, not because it's the only way of organizing. It's just that carbon is very good at that kind of chemistry. It's very common in the universe. Water is ubiquitous. We know, from the principles of life on earth, that all this stuff works and we know that it's thermodynamically favored. ...[J]ust statistically, I would expect, maybe 900 times out of a thousand that life would be organized in a similar way to life here. That's not to say it can't be different. It's just probably... going to be similar."
