how to refer destroyed object when instantiate using prefabs

I have been trying to solve the prob. since two days but unable to get it throught,please help me in referencing the player(as 3D sphere),which is been destroyed on collision for certain conditions to full fill(all are specified with the attachement).I want to destroy object on collion of 3 RED Stones (as 3D cubes),but at the same time i want to instantiate it as player’s life is reduced from 3 to 2 and so on.I have also used a 3D long rectangle for shooting purpose(target being player),but when the player is destroyed,these 3D long rectangles no more able to reference player.Help me please

Your question is hard to understand, but I believe the solution is to not destroy things in the first place. Just use renderer.enabled = false or gameObject.SetActive(false). One or the other of these is almost always preferable to Destroy, especially if you need not lose the reference to the object.
