Why is this function not returning a animation object?

Every time I click two times while having the the tool equipped it doesn't return the animation object,why?

Why is this function not returning the object?

Player = game.Players.LocalPlayer
Character = Player.Character
Tool = script.Parent
---------------------------------------------------------------------
function CreateAnimation(id,Humanoid)
	local AnimationName = "Animation_"..id
	local FoundAnimation = Humanoid:FindFirstChild(AnimationName)
	if not FoundAnimation then
		local Animation = Instance.new("Animation",Humanoid)
		Animation.Name = AnimationName
		Animation.AnimationId = "http://www.roblox.com/Asset?ID="..id
		return Animation
	else
		return Animation
		end
	end
---------------------------------------------------------------------
Tool.Equipped:connect(function(Mouse)
	print("Equipped")
	Mouse.Button1Down:connect(function()
		Humanoid = Character.Humanoid
		local Animation = CreateAnimation("169093883",Humanoid)
		local AnimationTrack = Humanoid:LoadAnimation(Animation)
		print(Animation)
	end)
	
end)
