It is used with hydrogen to form water and when mixed with nitrogen it forms all but about 1% of air.

We need oxygen to breathe . Without oxygen we would no be able to survive on earth. It is also used to create fires that warm us and provide power for our machinery and as a fuel in welding flames and rocket fuels.
