`UnityEngine.Camera.main' cannot be accessed with an instance reference, qualify it with a type name instead

New to C#, it’s pedantic. I’m used to Matlab. Basically `UnityEngine.Camera.main’ cannot be accessed with an instance reference, qualify it with a type name instead. In other words, it makes too much sense to be able to access the main camera by saying camera.main. How do I fix this?

using UnityEngine;
using System.Collections;

public class Building : MonoBehaviour {
public GameObject sphere1=null;

// Use this for initialization
void Start () {
	sphere1=Instantiate(Resources.Load("Prefabs/prefab_sphere")) as GameObject;
}

// Update is called once per frame
void Update () {
	var playerObject = GameObject.Find("Player");
	var playerPos  = (Vector3)playerObject.transform.position;
		
	// var cam  = camera.GetComponent(main);

	var buildingPos = playerPos + camera.main.WorldToScreenPoint(Vector3.zero);

	Debug.Log(playerPos);
	if(Input.GetMouseButtonDown(0))
		sphere1=Instantiate(Resources.Load("Prefabs/prefab_sphere"),buildingPos,Quaternion.identity) as GameObject;
		 

}

}

var cam = Camera.main;

It’s Camera.main (capital C) - to access the public static on the Camera class which refers to the Main Camera.

camera is a property returning a camera attached to the same gameObject as the script.

In C# static members are accessed using the class name and not instance names.
