Need help instantiating enemies between random locations

Trying to take a handful of enemies and spawn random ones in random spots of my side-scroller. below is my code and here is the error I'm reciving:

Assets/Scripts/SpawnEnimies.cs(19,25): error CS1502: The best overloaded method match for UnityEngine.Object.Instantiate(UnityEngine.Object, UnityEngine.Vector3, UnityEngine.Quaternion)' has some invalid arguments Assets/Scripts/SpawnEnimies.cs(19,25): error CS1503: Argument #1' cannot convert UnityEngine.GameObject[]' expression to type UnityEngine.Object'

Any suggestions?

using UnityEngine; using System.Collections;

public class SpawnEnimies : MonoBehaviour {

 public GameObject[] Enimies; //Assign platform pieces in the inspector
 public Vector3 spawnPoint; //Shorter way to grab the position of this platform
 

 void Start () {

     print (spawnPoint);

     int i = 0;

     while (i < 5)
     {
         spawnPoint = new Vector3(Random.Range(100.0F, 1000.0F), 70, Random.Range(100.0F, 1000.0F));
         Instantiate(Enimies, spawnPoint, Quaternion.identity);
         i++;
     }
 }
 

 void Update () {
     
 }

}
