In about 99.9% of the cases the answer of an error is in the error. You are part of those 99.9%. " life is not defined" You have not defined life in the tag list nor have you assigned it to the object. Since it does not exist. Again, you cannot just create things on the fly. Or make sure it is not Life.

What are you trying to destroy? Id it is the object you are colliding with use the col reference:

function OnCollisionEnter(col : Collision)
{ 
     if(col.CompareTag("life"))
         Destroy(col.gameObject);
}

If you need to find another object then you need:

Destroy(GameObject.FindGameObjectWithTag(“life”));

I recommend you to use the method from Unity. You cannot just create them on the fly.

once again, if i have 3 life, how can i destroy one by one using those tag??? assume that those 3 cube life have the same name called "life"...
