[CFrame] Why wont this position CFrame work???

#Localscript

The bullet wont even shoot from the correct target (EarthPart) in workspace. Why??

local Target = Mouse.Target
	local Dist = ((Target.Position-EarthPart.Position).magnitude)
	local Bullet = Create'Part'{BrickColor=BrickColor.new('New Yeller'),Parent=EarthPart,Name='Bullet',Anchored=true,CanCollide=false,Locked=true,FormFactor='Custom',Size=Vector3.new(.2,Dist,.2)}
	Bullet.CFrame = CFrame.new(EarthPart.Position,Target.Position)
	* CFrame.new(0,-Dist,0)
	local GunSound = Instance.new("Sound",workspace) GunSound.Pitch = 1 GunSound.Volume = 1 GunSound.Looped = false GunSound.SoundId = "rbxassetid://132456235"
	GunSound:Play()
	for i = 0,1.1 do
		Bullet.Transparency = Bullet.Transparency + .1
		Services.run.RenderStepped:wait()
	end
	Bullet.Touched:connect(function(obj)
	    if obj.ClassName == 'Model' then
	        if obj:FindFirstChild('Humanoid',true) then
	            obj.Humanoid.Health = obj.Humanoid.Health - 15
	        end
	    end
	end)
	Bullet:remove()

If I'm not mistaken, Z is the front face when working with CFrame.

Bullet.CFrame = CFrame.new(EarthPart.Position,Target.Position) * CFrame.new(0,0,-Dist)
