Oxygen was discovered by Joseph Priestly in 1774. It is from the Greek words //oxus// (acid) and //gennan// (generate). It is used by all living things on Earth to breathe and live. (so it affects our life by keeping us alive) We have it pumped in our blood. The first human to use it would have been the first human on Earth. It has other uses and properties like flammability and used to in air compressors. Oxygen is in the air it mixes with other gases in our atmosphere, so in air compressors it isn't the only gas working. The compressed air has a number of uses in machines such as bolting or filling up your tires.
