### Segment 1 (00:00 - 01:00) []

Maybe one star in a 100 thousand has a technical civilization more advanced than we. That's a few million civilizations in the galaxy. That's an awful lot. On the other hand, the distances between the stars are so great that it means the distance to the nearest one is a few hundred light years. So, they're not over in the next stellar county. They're very far away. And uh that's why listening for a message uh is going to be such an arduous and timeconsuming and expensive task because uh there are so many places to look. If there's a positive indication of life on Mars uh and it's not due to us dropping microorganisms on Mars and then detecting our own detritis. Uh that's why we sterilize spacecraft. Uh then I think it means that the origin of life is easy. it uh it has the greatest significance because uh if there are two places that you look at and you find life on both of them then it surely implies if those two events are independent that the origin of life does not require remarkably special or unlikely conditions and then I think many would be willing to take the grand leap to believing that uh that life is a common occurrence on innumerable planets of other stars in the galaxy.
