Why do these 4 elements make up most of living things?
Oxygen+Hydrogen = water, which has many special properties that make life possible
Carbon - its 4-bond tetrahedron properties make complex organic molecules possible
Nitrogen - its 3-bond properties are valuable
H is common (leftover protons from the Big Bang)
CNO are common in many types of supernovae.
