Episode notes

"I think unfortunately, even though that makes me sad, the way to pick it up is by studying life here on earth," he says. "It starts with very simple life that can be so different that it might be just right in front of our nose and we don't see it." He doesn't know if this theory will be verified or it would be discredited. But what I like about it is that it forces me to think on how do I look for life?"
