All the essential ingredients to make the DNA and RNA underpinning life on Earth have been discovered in samples collected from the asteroid Ryugu, scientists said Monday.
Sample size of 1, admittedly, but we’ve had life on earth for 4 billion years. We’ve had life capable of radio communications for about 50 years. That’s .0000000014% of the time life has existed. Maybe it wouldn’t be a bad assumption to think that only that proportion of stars would have even had the time to get to this stage.
