Raycast / Null Reference Exception

Hello, I have this code for a school project and I'm really a beginner in programming. It returns a null reference exception whenever I put it:

 if (hit.collider.CompareTag ("Player") && hit2.distance == 0) {
             Debug.Log ("Youdead");
         }

It's from a bigger code:

 void Raycasting(){
 
         Debug.DrawLine (sightStart.position, sightEnd.position, Color.magenta);
 
         RaycastHit2D hit = Physics2D.Raycast (new Vector2 (sightEnd.position.x, sightEnd.position.y), new Vector2 (-1, 0));
         RaycastHit2D hit2 = Physics2D.Raycast (new Vector2 (sightEnd.position.x, sightEnd.position.y), new Vector2 (1, 0));
         Debug.DrawLine (new Vector2 (sightStart.position.x, sightStart.position.y), hit.point, Color.blue); 
         Debug.DrawLine (new Vector2 (sightStart.position.x, sightStart.position.y), hit2.point, Color.green);
 
         if (hit.collider.CompareTag ("Player") && hit2.distance == 0) {
             Debug.Log ("Youdead");
         }

Do you have any solution to correct the Null Reference Exception?

Thanks.
