Bullet Being Created Multiple Times?

So I was trying to make a gun on roblox. I used instance.new to make the bullet but the instance fired multiple times. Can someone help me out? Please Respond as soon as possible.(here is the code)

local Players = game:GetService("Players")
local player = Players.LocalPlayer
local mouse = player:GetMouse()

script.Parent.Activated:Connect(function()


    mouse.Move:Connect(function()
        mouse.Button1Down:Connect(function()
            local Bullet = Instance.new("Part")
            wait(2)
        Bullet.Parent = workspace
                Bullet.CFrame = mouse.Hit

        end)    
    end)
end)
