Oxygen is already present in the earths atmosphere. Its presence is 21% in the entire composition of the atmospheric gases which comprises of many other gases and rare gases.

The simplest way to generate oxygen is by the process of electrolysis of water. It is process in which controlled direct current (DC) is passed through the water through metal electrodes. The water is composed of one part of oxygen and 2 parts of hydrogen. By process of electrolysis the oxygen and hydrogen molecules are separated and released at the electrodes. Two molecules of hydrogen are released at the negative electrode and one molecule of oxygen at the the positive electrode. This can be collected by making appropriate arrangements to collect the gas.

There are many other methods of generating oxygen, but electrolysis is the simplest one.
