Then there is no point, and we should probably not care that much.

Well, the planet will bounce back without us. Sure, it won’t be the same… but a billion years ago was pretty different from now.

Great Oxygenation Event: Around 2.4 billion years ago, a type of photosynthetic microorganism—cyanobacteria, often called blue-green algae—began producing large amounts of oxygen as a byproduct of photosynthesis. At the time, Earth’s atmosphere had almost no oxygen, and this new oxygen was actually toxic to most existing life. The result was it killed most of the life on earth including itself, and new life forms adapted to oxygen.

So in a few billion more years, whatever intelligent life pops up will look back and think of us as just another algae problem.

Screw humanity.
