why won't local debounce = false work?

I don't know why, but the debounce on this script wont work. I'm not very good with debounce, so i don't know what's failing. Even though I have the debounce script, this script will play a million times when touched

--Variables
function fade()
	script.Parent.Parent.Enabled = true
	for i = 0, 1, 0.05 do
		script.Parent.TextTransparency = i
		wait(0.05)
	end
	for i = 1, 0, -0.05 do
		script.Parent.TextTransparency = i
		print(i)
		wait(0.05)
	end
	script.Parent.Parent.Enabled = false
	return
end

local debounce = false
--Variables

workspace.Earth.Earth.Touched:connect(function()
	if debounce == false then
		debounce = true
		-- script.Parent.Text = "Earth"
		fade()
	end
end)

workspace.Earth.Earth.TouchEnded:connect(function()
	if debounce == true then
		debounce = false
		script.Parent.Parent.Enabled = false
		wait(1)
		debounce = false
	end
end)

I don't know what's wrong.

A player touches a part infinite times in a second, that being said, if you have the same part connected to two touched function then the debounce is completely useless, the value will change and the other function will run, instead of using the same part, use two different parts in the same script and it should work perfectly.
