Raycast not visible

Hey everyone,
Im making an RTS and im trying to begin by having a raycast able to be visible on click so that i can detect if a unit is being selected by the mouse (if there is an easier way let me know). Anyways, its not showing up, and I feel ive tried about everyting. Here is my code below:

if (Input.GetMouseButtonDown (0)) { //if left click...
			startClick=Input.mousePosition; //give the position

			//test code
			Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition); //trying to single select
			RaycastHit hit;
			Debug.DrawRay (ray.origin, startClick * Mathf.Infinity, Color.red);
			if (Input.GetMouseButtonDown (0)) {
				if(Physics.Raycast(ray,out hit, Mathf.Infinity)){

DrawRay only shows up in the Scene view, not in the Game view.

It’s only for debugging.

You looking in the Scene view? Also, zoom way out, maybe your coordinates are off.
