Is There A Simple Solution To The Fermi Paradox?

Season 11 Episode 4 | 18m 50s

Does this also explain why there are no aliens?

Around 2 billion years ago, life had plateaued in complexity, ruined the atmosphere, and was on the verge of self-annihilation. But then something strange and potentially extremely lucky happened that enabled endless new evolutionary paths. The first eukaryote cell was born. This may also explain why there are no aliens.
