How can I Instantiate a parent object in a child object?

I am creating a code that makes an enemy drop items, but the problem is that I dont want to instantiate the item as a child of the enemy

For example:

Enemy1 <-- Parent (Then, when its killed generates a child object, which is the item)

Item <-- Child of enemy1

And since the enemy1 was killed, it will be destroyed, but the problem is that it also destroys the Item that it drops, since its a child from enemy.

The code I am using for this is:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class EnemyControl : MonoBehaviour , ILivingThing{
 
     public Enemy thisEnemy;
     
     void Update () {
         //Some artificial intelligence here...
         Damage(1);
     }
 
     public void Damage(float damageAmt){  //Implemented from ILivingThing
         thisEnemy.Damage (damageAmt);
         if (thisEnemy.Health <= 0) {
             dropItem ();
             Kill ();
         }
     }
 
     public void Heal(float healAmt){    //Implemented from ILivingThing
         thisEnemy.Heal (healAmt);
     }
 
     public void Kill(){    //Implemented from ILivingThing
         thisEnemy.Kill ();
         //Destroy (gameObject);
     }
 
     void dropItem(){
         GameObject Item = Instantiate (Resources.Load ("Prefabs/Items/Item1"), gameObject.transform) as GameObject;
         Item.GetComponent<ItemControl> ().thisItem = new Item1();
     }
 }

How can I Instantiate a GameObject on "top of hierarchy" to get rid of this problem?
