Why oxgen support combustion?

Because oxygen is the strongest oxidizer which accept electrons
 
Specifically, combustion requires three things:
1) Fuel : The thing that burns. This is is often a hydrocarbon, or other organic molecule. The simplest possible fuel is pure hydrogen gas.
2) Energy : What gets the reaction started, which is true of most chemical reactions. Note that this so-called
activation energy is usually much less than the energy ultimately released from combustion. This is like rolling a boulder some distance in order to roll it down a hill, which releases much potential energy.
3) Oxidizer : The molecule that accepts electrons. It turns out that combustion requires the fuel to be oxidized , that is, it donates electrons. So we need something to accept the electrons, and that's the oxidizer, which is then
reduced .
Oxygen is a great oxidizer because it is so electronegative , which means it really wants to accept electrons. Only fluorine is more electronegative, and fluorine is a superb oxidizer: blow fluorine gas at nearly any substance and it bursts into flames
