Currently oxygen is about 20% of the atmosphere. In the Carboniferous period, 60 million years ago, it’s thought to have gotten as high as 30%.
Oxygen is highly reactive, and the 02 configuration is not particularly stable, so over time it gets locked up in other molecules, which are then burred or deposited at the bottom of bodies of water.
