Why wont the fireball do any damage?

I have a tool that when activated will shoot a fireball and when that collides with a player it will deal damage to the targets humanoid. This is a simulator game (like superpower training simulator) so the damage of the fireball will be different depending on the players fist strength but for some reason it doesn't deal any damage. Here's the script:

local Tool = script.Parent
local Cooldown = false
local CDTime = 1.5



Tool.RemoteEvent.OnServerEvent:Connect(function(Player,Mouse)
    if Cooldown then return end 

    spawn(function()
        Cooldown = true 
        wait(CDTime)
        Cooldown = false 
    end)

    local sphere = game.ReplicatedStorage.Abilities.EnergySphere.Sphere1:Clone()
    sphere.Parent = game.Workspace
    local Position = Player.Character.Head.Position + CFrame.new(Player.Character.Head.Position).lookVector * 1 
    sphere.CFrame = CFrame.new(Position)
    sphere.Orientation = Player.Character.Head.Orientation
    sphere.CanCollide = false
    sphere.Anchored = false
    sphere:SetNetworkOwner(Player)
    local BodyVelocity = Instance.new("BodyVelocity",sphere)
    BodyVelocity.Velocity = Mouse.lookVector * 50
    BodyVelocity.MaxForce = Vector3.new(1e8,1e8,1e8)
    game.Debris:AddItem(sphere,1.8)


    sphere.Touched:Connect(function(hit)
        if hit.Parent == Player.Character then return end
        if hit and hit.Parent:FindFirstChild("Humanoid") then 
            local EnemyHum = hit.Parent:FindFirstChild("Humanoid")
            Player.Data.Strength:GetPropertyChangedSignal("Value"):Connect(function()
                EnemyHum:TakeDamage(Player.Data.Strength.Value)
            end)
            Tool.Explosion:Play()
            sphere:Destroy()

        end
    end)
end)
