The early universe consisted of mostly hydrogen and helium with very few heavier elements. Stars formed from those light elements and as they burned up their fuel they formed heavier elements such as carbon, nitrogen and oxygen. Those heavier elements were then dispersed via stellar winds, novae and supernovae and then ultimately ended up in planets and of course, us.
