error CS0117: `UnityEngine.Physics' does not contain a definition for `RayCast'

i am following a basic tutorial for raycasting in first person and have the code done the way its shown in the tutorial but for some reason the error error CS0117: UnityEngine.Physics' does not contain a definition for RayCast' comes up.

i have tried importing it specifically using UnityEngine.Physics.Raycast

the only other script i have is the prefab firstpersoncontroller from the standard assets also so no class is called physics in it

 using UnityEngine;
 using System.Collections;
 
 public class Select : MonoBehaviour {
     public RaycastHit hit;
     // Use this for initialization
     void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {
     Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0));

     if (Physics.RayCast(ray, out hit, 10))
     {
         Debug.Log("Hit");
     }
 }
 }

i have searched for an answer to this and they do not solve my issue
