GameObject cant find definition for anything, 2 suggesteds,GameObject only has Equals and Reference Equals

GameObject’s only suggesteds are Equals and Reference Equals, everything else it cant find a definition for
using System.Collections;

using UnityEngine;

public class CameraMotor : MonoBehaviour {

private Transform lookAt;
void Start () {
	GameObject.FindGameObjectWithTag ("Player");
}


void Update () {
	
}

}

,using System.Collections;

using UnityEngine;

I just want my camera to follow the player but GameObject’s suggesteds only return Equals and Reference Equals and cant find a definition for anything else I try.

public class CameraMotor : MonoBehaviour {

private Transform lookAt;
void Start () {
	GameObject.FindGameObjectWithTag("Player")
}


void Update () {
	
}

}

Of course, you have to make a variable where you store the object, make a variable GameObject and equal it to the find.
GameObject objIWantToLook;
void Start(){
objIWantToLook=GameObject.FindGameObjectWithTag(“Player”);
}
