[00:00:00]Take a deep breath. It's refreshing, right?

[00:00:04]Just so you know, the oxygen you just breathed in billions of years ago was the deadliest poison in the universe.

[00:00:12]2.4 billion years ago, Earth had no oxygen at all.

[00:00:17]The first living creatures at that time, a type of ancient bacteria, lived peacefully without oxygen.

[00:00:24]Until finally, a group of selfish bacteria called cyanobacteria emerged, which began photosynthesizing and releasing oxygen everywhere.

[00:00:34]To other bacteria, it was toxic waste.

[00:00:38]This event caused a mass extinction of almost all living things on Earth.

[00:00:43]So, the gas you now need to breathe was once the greatest weapon of mass destruction in Earth's history.

[00:00:50]The plot twist is quite fitting, isn't it?
