how do i get the viewid of the object that my prefab collided with? PhotonNetwork

im using photon network, and im bashing my head up against the wall trying to figure out how to do this. i want it so that when the object collides with another, it reads the viewid of the object it hit and i can deduct health points. reason why i need the view id, is because it belongs to another player. im extremely confused. if you can give me an example of a better way to get this done, please dont hesitate to show me :).

 using UnityEngine;
 using System.Collections;
 
 public class fireballexplosion : Photon.MonoBehaviour {
     float lifespan = 3.0f;
     
     // Use this for initialization
     void Start () {
         //note: change for other maps ----
         GameObject _map1 = GameObject.Find ("Map1");
         GameObject _warrior = GameObject.Find ("6102024(Clone)");
         GameObject _Mage = GameObject.Find ("MagePlayer(Clone)");
         Physics.IgnoreCollision (_map1.collider, collider);
         //Physics.IgnoreCollision (_warrior.collider, collider);
         //Physics.IgnoreCollision (_Mage.collider, collider);
     
     }
     
     // Update is called once per frame
     void Update () {
         lifespan -= Time.deltaTime;
         
         if(lifespan <- 0) {
             Explode();
         }
      }
     
     [RPC] void OnCollisionEnter (Collision collision) {
         //Destroy (GameObject);
         if(collision.gameObject){
             //this is all failed attempts to try to do this..
             print("This collider collided with: " + pView);
             
              foreach (ContactPoint contact in collision.contacts) {
                 print(contact.thisCollider.name + " hit " + contact.otherCollider);
                 Debug.DrawRay(contact.point, contact.normal, Color.white);
             
             }
             
             lifespan = 0.25f;
             //Destroy (gameObject);
             
             
             
         }
     }
     
     
     void Explode () {
         Destroy (gameObject);
     }
 }
