How do you make this incinerator script that destroy boxes right ?

I'm making a incinerator where if you hold a a specific tool (BOX) it will destroy it but for some reason this script doesn't mark anything , the output doesn't say anything please help ?

local box = game.Workspace.BOX
local thing = script.Parent
local player = game.Players.LocalPlayer
thing.Touched:Connect(function()
    if player.Backpack:FindFirstChild("BOX") then
       box:Destroy()
        print("Removed the players Item")
    else if player.Backpack.Box ==false then
          player.Backpack.BOX = false
      end
    end
end)

PS this is a local script BTW
