Name 2 reasons why oxygen was vital for the formation of living things

To survive on earth, oxygen is the single most vital element. You can survive for couple of days without taking nitrogen and hydrogen but you can’t survive without oxygen for more than few minutes.

Two main reasons which describe the importance of oxygen in the creation of living beings are:

-To generate energy in the form of ATP (Adenosine triphosphate)

-To form water (essential to conduct reactions in human body)
