Need help with destroying 2d gameobject with raycast2d C#

Unity Engine
1

Im trying to figure out how to destroy gameobject(ball) with other gameobject(ant) on mouseclick. I have 2 objects and both have Rigidbody 2d + Circe collider 2d. This script is attached to gameobject(ant)

this destroys object even im not clicking it on top of the ant gameobject so it destroys from everywhere i click.

using UnityEngine;
using System.Collections;

public class DestroyOnClicked : MonoBehaviour {

    public GameObject ant;

    void FixedUpdate ()
    {
        if (Input.GetMouseButtonDown(0))
        {
            RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
           
            if(hit.collider != null)
            {
                if(hit.collider == gameObject.collider2D);
                {
                    Destroy(gameObject);
                }
            }
        }
    }
}
