How do I assign my item's parent to my player's backpack?

debounce = true

script.Parent.Touched:Connect(function(hit)
    local humanoid = hit.Parent:FindFirstChild('Humanoid')
    if humanoid ~= nil and debounce then
        local player = game:GetService("Players"):GetPlayerFromCharacter(hit.parent)
        print(player.name)
        hit.Position = Vector3.new(22.176, 1.5, -18.612)
        local sword = game.Workspace.ClassicSword:Clone()
        sword.Parent = game.Players.player.Backpack
        print(sword.parent)
        debounce = false

    end
end)

I'm getting lost in the layers, this doesn't seem to work. I try to make a copy of the sword and then assign its parent to the player's backpack. Why doesn't this work?
