Why is the Player not registering when Hit?

Hello!

Adapted a Walking NPC/Fireball shooter script from DutchDeveloper. Its a Script placed inside an NPC, the NPC walks around, shoots fireballs. Only one slight problem - it does not register when it Hits a Player. Line 64-69 is the relevant parts, but I included the entire script just in case.

No errors, when i put some Prints in to show whats being hit, it'll read back "baseplate" or "wall" or whatever else it hits, but never a Player, or anything with a Humanoid in it.

Thoughts? Advice? Many thanks in advance!

Script:

local Humanoid = script.Parent:WaitForChild("Humanoid")
local HumanoidRootPart = script.Parent:WaitForChild("HumanoidRootPart")

local WalkRange = 20
local FireballSpeed = 100
local Damage = 25

local Closest = nil

spawn(function()
	while true do
		wait()
		if Closest ~= nil then
			HumanoidRootPart.BodyGyro.CFrame = CFrame.new(HumanoidRootPart.Position, Vector3.new(Closest.Character.HumanoidRootPart.Position.X, HumanoidRootPart.Position.Y, Closest.Character.HumanoidRootPart.Position.Z))
		end
	end
end)

while true do
	wait(2)
	local RandomValue = math.random(0,10)
	local List = {}
	
	for i,v in pairs(game.Players:GetChildren()) do
		if v and v.Character then
			local Distance = (HumanoidRootPart.Position - v.Character.HumanoidRootPart.Position).Magnitude
			table.insert(List, {v, Distance})
		end
	end
	
	table.sort(List,function(A,B)
		return A[2] <= B[2]
	end)
	
	if #List >=1 then
		Closest = List[1][1]
	if RandomValue > 0 and RandomValue < 6 then
		local RandomWalkPosition = Vector3.new(math.random(-WalkRange,WalkRange),0, math.random(-WalkRange,WalkRange))
		Humanoid:MoveTo(HumanoidRootPart.Position + RandomWalkPosition)
	else
					
		local Fireball = Instance.new("Part")
		Fireball.Anchored = false
		Fireball.Shape = "Ball"
		Fireball.Size = Vector3.new(5,5,5)
		Fireball.TopSurface = Enum.SurfaceType.Smooth
		Fireball.BottomSurface = Enum.SurfaceType.Smooth

		Fireball.Material = Enum.Material.Sand
		Fireball.BrickColor = BrickColor.new("Institutional white")
		Fireball.CFrame = HumanoidRootPart.CFrame*CFrame.new(0,0,-10)
		Fireball.Parent = workspace
		Fireball.CanCollide = false
		
		local BV = Instance.new("BodyVelocity")
		BV.MaxForce = Vector3.new(100000,100000,100000)
		
		local Origin = HumanoidRootPart.Position
		BV.Velocity = (List[1][1].Character.HumanoidRootPart.Position - Origin).unit * FireballSpeed
		BV.Parent = Fireball
		spawn(function()
			wait(2)

		Fireball.Touched:Connect(function(Hit)  -- STARTS HERE
			if Hit and Hit.Parent and Hit.Parent:FindFirstChild("Humanoid") then  
				Hit.Parent.Humanoid:TakeDamage(Damage)	
				end
					Fireball:Destroy()	
			end)
		end)
		wait(2)
		end
	end
