If all the atoms and molecules are aimingaim for stability and equilibrium, then what is the reason behind why the atoms/molecules feelingdo they feel the need to reverserevert back into itstheir original state and back to square one ifonce they have already found stability (example?

Example: I2 + H2 --> 2HI)? what's causing this behavior that$\ce{I2 + H2 \to 2HI}$

What causes reversible reactions to exist? 

Because "It"it is generally said that reactants react so that they can achieve a lower energy state."
