How do you summon a part on a mouse's target?

Hi, I am trying to make a script that summons a part on a players target. The issue I am having is that when I tell the part to go to the target (mouse target) an error appears on the output. It says

19:56:36.799 - ContextActionService: Unexpected error while invoking callback: Players.turbomegapower12345.PlayerScripts.ZeusPowers:22: bad argument #3 to 'CFrame' (CFrame expected, got Vector3)

But when I do CFrame, another error appears

20:00:30.572 - ContextActionService: Unexpected error while invoking callback: Players.turbomegapower12345.PlayerScripts.ZeusPowers:22: bad argument #1 to 'new' (Vector3 expected, got nil)

How do I fix these errors and make a part summon on the mouse target?

Here is my script!

local player = game.Players.LocalPlayer
local character = player.CharacterAdded:wait()
local humanoid = character.Humanoid
local torso = character.UpperTorso
local mouse = player:GetMouse()


local target = mouse.Target



local God = player.PlayerGui.ChooseCharacter.God
--BREAKLINE--

function onKeyPress(actionName, userInputState, inputObject)
    if userInputState == Enum.UserInputState.Begin then
        if inputObject.KeyCode.Name ==("E") then
	if God.Value ==("Zeus") then
		print("THUNDERBOLT!")
		local Thunder = Instance.new("Part",workspace)
	    Thunder.CFrame = CFrame.new(target)
	 
		
	end
	
end
    end
end

game.ContextActionService:BindAction("keyPress", onKeyPress, false, 
   Enum.KeyCode.R,
   Enum.KeyCode.E)
