Cannot implicitly convert type `UnityEngine.GameObject[]' to `UnityEngine.GameObject'

How could i fix this problem? Here is the code:

using UnityEngine;
using System.Collections;

public class EnemyAI : MonoBehaviour {
	public Transform target;
	public int moveSpeed;
	public int rotationSpeed;
	private Transform myTransform;
	void Awake() {
		myTransform = transform;

	// Use this for initialization
	void Start () {
		GameObject go = GameObject.FindGameObjectsWithTag("Player");
		target = go.transform;
	// Update is called once per frame
	void Update () {

um your assigning an array to a singular game objects

 GameObject go = GameObject.FindGameObjectsWithTag("Player");

this line should be

GameObject go = GameObject.FindGameObjectWithTag("Player");


GameObject go = GameObject.FindGameObjectsWithTag("Player")[0];

Also for the Mods out there ,for some weird reason FindGameObjectWithTag isn’t documented, only its array is. Why is this?
