Interact with Objects around the player

So I made a method that shall damage Objects with the tag Enemy near the player. But it doesn't work correctly, i dont actually know why i made gave the enemy the tag player, and attached both scripts to player and enemy

 public int damage = 50;
 public float range = 1f;
 private List <GameObject> enemys = new List <GameObject>();

 void Update () 
 {
 
         if(Input.GetButton("Fire0"))
         {
             Attack();
         }
 }

     protected void Attack()
     {
 
         Vector3 center = transform.position;
         
         Collider[] hitColliders = Physics.OverlapSphere(center, range);
 
         
         int i=0;
 
         while(i<hitColliders.Length)
         {
             
             if(hitColliders[i].tag=="Enemy")
             {
                 enemys.Add(hitColliders[i].gameObject);
             }
             i++;
         }
 
         for(i=0; i < enemys.Count; i++)
         {
             enemys[i].GetComponent<Enemy>().recieveDmg(damage);
         }
     }


 public class Enemy : MonoBehaviour
 {
     public int life = 100;
 
     void Update()
     {
         if(life == 0)
         {
             gameObject.SetActive(false);
         }
     }
 
     public void recieveDmg(int damage)
     {
         life -= damage;
     }
 
 }
 

I only copied the important parts of the code, if you need anything more pls let me know :/
