Make AI Shoot at Player

Hey Guys,

I'm trying to make simple space game that have a mother ship(player) and enemys.

I wanted the Enemy object to shoot at mother ship when they saw it. but I couldn't. Instead I had enemies shoot at every 2 seconds. But It makes the enemy look stupid ^^

I looked previous subjects but there was nothing about it. Any help will be appreciated. Thanks in advance

Those are my code :

 public class Enemy : MonoBehaviour
 {
     [SerializeField] float health = 100;
     [SerializeField] GameObject fireball;
 
     [SerializeField] float timeBetweenShots;
     [SerializeField] float startTimeBetweenShots;
 
     
 
 
 
 
 
 
     private void OnCollisionEnter2D(Collision2D other)
     {
         DamageDealer damageDealer = other.gameObject.GetComponent<DamageDealer>();
         DamageProcess(other, damageDealer);
 
     }
 
     private void DamageProcess(Collision2D other, DamageDealer damageDealer)
     {
         health -= damageDealer.GetDamage();
         Destroy(other.gameObject);
         if (health == 0)
         {
             Destroy(gameObject);
         }
     }
     private void Start()
     {
         timeBetweenShots = startTimeBetweenShots;
 
         
        
     }
 
 
     private void Update()
     {
         MakeEnemyFire();
         
     }
 
 
     private void MakeEnemyFire()
     {
         if (timeBetweenShots <= 0)
         {
 
             
             
             Instantiate(fireball, GameObject.FindGameObjectWithTag("EnemyFire").transform.position, Quaternion.identity);
 
             
             
             timeBetweenShots = startTimeBetweenShots;
         }
         else
         {
             timeBetweenShots -= Time.deltaTime;
         }
 
     }
 }
