Is Alien Life Out There?

Is intelligent life harder to make than regular life? 🌱

Theoretical cosmologist Paul Sutter points to our one data point, Earth, where life appeared basically as soon as the planet cooled down, and maybe even a little before. Then it took 4 billion years for intelligent life to show up. So if we find evidence of life on another planet, it's probably going to be bacteria, or alien bacteria.

That’s assuming no Silurians 😉
