How do I use ScreenPointToRay?

Alright, so recently I've been messing around with the Camera. I want to find the 3D position the player is looking at using the camera. This is the code I'm using:

c = game.Workspace.CurrentCamera
c.CameraSubject = game.Workspace.NewCam
c.CameraType = "Attach"


print(c:ScreenPointToRay(0,0))

After I press 'Play' in Studio, I check the coordinates that are printed into the output. This is what gets printed:

{-0.989541292, 30.9928341, 11.3838854}, {-0.759665072, 0.218074307, -0.612660289}

The coordinates are always a bit different. How do I use 'ScreenPointToRay' to find the 3D position the player is looking at?

The full script:

wait()
plr = game.Players.LocalPlayer
inputS = game:GetService("UserInputService")
pressed = false
mouse = plr:GetMouse()

c = game.Workspace.CurrentCamera
c.CameraSubject = game.Workspace.NewCam
c.CameraType = "Custom"

plr.CameraMaxZoomDistance = 0

print(c:ScreenPointToRay(0,0).Direction)


-- ChatScript, CameraScript, ControlScript

plr.PlayerScripts:WaitForChild("ChatScript")
plr.PlayerScripts.ChatScript:Destroy()
plr.PlayerScripts.ControlScript:Destroy()

inputS.InputBegan:connect(function(i, gameProcessedEvent)
    if i.KeyCode == Enum.KeyCode.D then
        for i=1,15,1 do
            game.Workspace.NewCam.CFrame = game.Workspace.NewCam.CFrame + Vector3.new(1,0,0)
            wait(0.001)
        end
    elseif i.KeyCode == Enum.KeyCode.A then
        for i=1,15,1 do
            game.Workspace.NewCam.CFrame = game.Workspace.NewCam.CFrame + Vector3.new(-1,0,0)
            wait(0.001)
        end
    elseif i.KeyCode == Enum.KeyCode.W then
        --for i=1,15,1 do--
            game.Workspace.NewCam.CFrame = mouse.Hit
            wait(0.001)
        --end
    elseif i.KeyCode == Enum.KeyCode.S then
        for i=1,15,1 do
            game.Workspace.NewCam.CFrame = game.Workspace.NewCam.CFrame + Vector3.new(0,-1,0)
            wait(0.001)
        end
    elseif i.KeyCode == Enum.KeyCode.G then
        print(c:ScreenPointToRay(0,0).Direction)
    end
end)
