How do i make a Part look at the spot where the mouse clicked?

I'm trying to make a spaceship (but i'm testing with just a seat), when you sit in the spaceship, you can click in whatever place in the screen & the spaceship will look at the spot you clicked, i need help.

(btw if you played Moon Tycoon, and you have a spaceship, you know what i'm talking about.)

Here's the script i used in my place

local player
local mouse

local function onClicked()
	script.Parent.CFrame = CFrame.new(script.Parent.Position, mouse.Hit.Position) --Script.Parent is the seat
end

script.Parent.Touched:connect(function(hit)
	if hit and hit.Parent and game.Players:FindFirstChild(hit.Parent.Name) then
		player = game.Players:FindFirstChild(hit.Parent.Name)
		
		mouse = player:GetMouse()
		
		mouse.Button1Up:connect(onClicked)
	end
end)

but it doesn't work!

if you have a better idea, or if you know what to do here, tell me plz! :c Please! If someone knows how to make the Moon Tycoon's Spaceship, TELL ME! ...or if you know how to edit the Personal Rocketship without all the Tool stuff, and making it just for a seat
