Enemy Projectile Script Won't Shoot Closest Object

Question

I Have been trying to figure out how the Enemy doesn't return multiple GameObjects it only returns one.Im not sure whether it is my Bullet script that it allows only one object to return. I'm currently trying to develop a Game with multiple players like Slither.io so I'm not sure if the performance is affected I would like to use (List Function) but dont know where to start and I'm using a later version Unity 2017.3.1f1. Much Appreciated for your help.The scripts are below.

public class RandomAIProjectile
{
    private GameObject[] target;
    
    public float speed;
    
    Rigidbody2D bulletRB;
    
    public GameObject explosionEffect;
    
    // Find Targets Section.
    void Start () 
    {
        if (target == null)
            target = GameObject.FindGameObjectsWithTag("Player");
        
        for (int i = 0; i < target.Length; i++) 
        {
            bulletRB = GetComponent<Rigidbody2D> ();
            
            Vector2 moveDir = (target[i].transform.position - transform.position).normalized * speed;
            
            bulletRB.velocity = new Vector2 (moveDir.x, moveDir.y);
            
            Destroy (this.gameObject, 2);
        }
        
    }
    
    private void OnTriggerEnter2D(Collider2D other)
    {
        // Decoy Script To Destroy Players.
        if (other.gameObject.GetComponent<BlackthronpodDiePlayer>() != null)
        {
            Destroy (other.gameObject);
            Destroy (gameObject); 
        }
        // Damage Effect.
        if (other.gameObject.tag == "Player") {
            Instantiate (explosionEffect, transform.position, Quaternion.identity);
            Destroy(gameObject);
        }
        // Player (Bullet) Destroy Enemy.
        if (other.CompareTag ("Bullet"))
        {
            Destroy (other.gameObject);
            Destroy (gameObject); 
        }
        
        
    }
}

Here is the Player Script

public class RandomAIEnemy

        //Random Movement Reference

    }

    private bool TryGetClosestPlayer(out GameObject closest)
    {

    }

                waitTime -= Time.deltaTime;

Make sure that you have Rigidbody2d attached on your enemy and player. And also, is there any error coming in the code?
