Why doesn't the Touched Event activating?

I'm making a fireball script where you press Q to fire, but the damage part won't activate(Touched Event not activating).

local Player = script.Parent.Parent
local mouse = Player:GetMouse()

function Jutsu(key)
        if key:lower() == "q" then
            print("q activated")
-------------------------[Chakra Removal]--------------------------------
Player.Backpack.cpvalue.Value = Player.Backpack.cpvalue.Value - 5


-------------------------[Jutsu]-----------------------------------------
Flame = Instance.new("Part", Workspace)
Flame.CFrame = Player.Character.Torso.CFrame * CFrame.new(0,0,-5) * CFrame.Angles(33,0,0)
Flame.Shape = ("Ball")

MeshFlame = Instance.new("SpecialMesh", Flame)
MeshFlame.Scale = Vector3.new(2, 4, 2)
MeshFlame.MeshType = "FileMesh"
MeshFlame.MeshId = "http://www.roblox.com/asset/?id=25212400"           
MeshFlame.TextureId = "http://www.roblox.com/asset/?id=25212235"    

-------------------------[Velocity]--------------------------------------       
Movement = Instance.new("BodyVelocity", Flame)
Movement.maxForce = Vector3.new(math.huge, math.huge, math.huge)
Movement.velocity = Player.Character.Torso.CFrame.lookVector*40

------------------------[Effect]-----------------------------------------
function onTouched(Hit)
    print("Got Touched")
    if Hit.Parent:FindFirstChild("Humanoid") ~= nil then
        Hit.Parent.Humanoid.Health = Hit.Parent.Humanoid.Health - 20
    else
        Boom = Instance.new("Explosion", Flame)
        Boom.Position = Flame.Position

    end
end
Flame.Touched:connect(onTouched)    
-------------------------[Cooldown]--------------------------------------
            script.Disabled = true
            wait(20)
            script.Disabled = false



        end

    end

    mouse.KeyDown:connect(Jutsu)
