sprite changes z position without any input to do so

Question

im making a 2d platformer and i have a patrolling enemy but for some reason he changes z position even though i didn't say to and it makes his z position behind the camera so he doesn't render

heres the code

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class EnemyPatrol : MonoBehaviour {
 
     public float speed;
     public float distance;
 
     private bool movingRight = true;
 
     public Transform groundDetection;
 
 
     void Update()
     {
         transform.Translate(Vector2.right * speed * Time.deltaTime);
 
         RaycastHit2D groundInfo = Physics2D.Raycast(groundDetection.position, Vector2.down, distance);
         if (groundInfo.collider == false)
         {
             if (movingRight == true)
             {
                 transform.eulerAngles = new Vector3(0, -180, 0);
                 movingRight = false;
             }else
             {
                 transform.eulerAngles = new Vector3(0, 0, 0);
                 movingRight = true;
             }
         }
 
     }
 }

try this

 using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
  public class EnemyPatrol : MonoBehaviour {
  
      public float speed;
      public float distance;
  
      private bool movingRight = true;
  
      public Transform groundDetection;
  
  
      void Update()
      {
          transform.position = new Vector3(transform.position.x+ speed *Time.deltaTime,
 transform.position.y,transform.position.z);
 );
  
          RaycastHit2D groundInfo = Physics2D.Raycast(groundDetection.position, Vector2.down, distance);
          if (groundInfo.collider == false)
          {
              if (movingRight == true)
              {
                  transform.eulerAngles = new Vector3(0, -180, 0);
                  movingRight = false;
              }else
              {
                  transform.eulerAngles = new Vector3(0, 0, 0);
                  movingRight = true;
              }
          }
  
      }
  }
