Destory a single prefab when hit with Raycast

Hello, I am having an issue with Destroying a single prefab by lowering a single prefabs int to 0 without doing so to all other prefabs.

So the player "shoots" at a enemy that has a certain amount of "health", once it hits 0 the gameObject is destroyed. But my script takes the amount of "Damage" from all prefabs and not just the one that is being hit.

Here is the shooting script

     void FixedUpdate() {
         if (shooting) {
             shooting = false;
             flash.GetComponent<ParticleSystem>().Play();
 
             RaycastHit hit;
             Debug.DrawRay(transform.position, -transform.right, Color.green, 50f);
             if(Physics.Raycast(transform.position, -transform.right, out hit, 50f)) {
                 if(hit.transform.tag == "Enemy") {
                     Instantiate(impact, hit.point, transform.rotation);
 
                     enemyAttack.enemyHp -= 5;
                     if(enemyAttack.enemyHp < 0) {
                         Destroy(hit.collider.gameObject);
                     }
                 }
             }
         }
     }

The enemies Health is being controlled by a script that is on the prefabs. It is just

 public static int enemyHp = 200;

This at some degree does work, if the player shoots at an enemy enough then it will be destroyed but all other prefabs enemyHp is at 0. So what is taken from on prefab is taken from the others. and then each prefab is destroyed with a single hit after that.

Thank you for any help guys
