Because, their valency is zero.
ie., their outer shell (orbital) of electrons is "full", significantly limiting their ability to form chemical bonds. (A chemical bond is essentially a region lying between two atoms with a maximum probability for electrons to be present. The electrons in the 'bond' are kinda shared between both the atoms, and they keep the repelling nuclei of the two atoms together by being electrostatic-ally attracted to both. In quantum chemistry (using Schroedinger's equation), it is seen that, the state with the 'orbitals' being filled have a 'lower free energy' than states with unfilled orbitals. Atoms without filled orbitals react so as to achieve this 'lower energy' stable state. This is explained by the valence-bond theory/molecular orbital theory models).
All the noble gases have all their orbitals full, and hence their 'unfilled states in the orbitals available for bonding' (valency) is zero. This significantly reduces their ability to bond with other atoms. This is why, noble gases are very unreactive.

We know that elements of group 0 are called noble or inert gases they have fulfilled their outer electronic configuration it means they have already gained their stability, hence they are chemically unreactive
