error CS0101: The namespace `global::' already contains a definition for `SceneManagerLoadScene'

Hi! I was just making a project, however, i wanted 2 ways to load a scene. 1. on click in UI. 2. clicking on a game object. However, unity keeps saying I have 2 scripts with the same public class: SceneManagerLoadScene. How do i fix this???

Here are` using System.Collections; using System.Collections.Generic; using UnityEngine;

public class SceneManagerLoadScene : MonoBehaviour {

 // Use this for initialization
 void OnMouseDown () {
     
     SceneManager.LoadScene(CC);
     
 }
 
 // Update is called once per frame
 void Update () {
     
 }

} ` the 2 scripts

 using UnityEngine;
  using UnityEngine.SceneManagement;
  
  public class SceneManagerLoadScene : MonoBehaviour
  {
      public void NextLevelButton(int index)
      {
          SceneManager.LoadScene(index);
      }
  
      public void NextLevelButton(string CC)
      {
          SceneManager.LoadScene(CC);
      }
  }
