Fireball is not a valid member of ReplicatedStorage "ReplicatedStorage"?

For some reason when im presing the key to fire the fireball nothing happens and this error appears in the output tab

here are my scripts

local fireball = game.ServerStorage:WaitForChild("FireBall")

game.ReplicatedStorage.Fireball.OnServerEvent:Connect(function(player,CFrame)

    local character = player.Character
    local newFireball = fireball:Clone()
    newFireball.CFrame = character.HumanoidRootPart.CFrame

    local bodyVelocity = Instance.new("BodyVelocity")
    bodyVelocity.MaxForce = Vector3.new(5000,5000,5000)
    bodyVelocity.Velocity = (character.HumanoidRootPart.CFrame.lookVector*250)
    bodyVelocity.Parent = newFireball

    newFireball.Parent = workspace

    local touchConn

    touchConn = newFireball.Touched:Connect(function(hit)
        if hit.Parent:FindFirstChild("Humanoid") then
            if hit.Parent.Name ~= player.Name then
                hit.Parent:BreakJoints()
                if touchConn ~= nil then touchConn:Disconnect() end
                newFireball:Destroy()
            end
        end
    end)

    wait(2)

    if touchConn ~= nil then touchConn:Disconnect() end
    newFireball:Destroy()

end)

local UserInputService = game:GetService("UserInputService")

local player = game.Players.LocalPlayer

local character = player.Character or player.CharacterAdded:Wait(1)

local debounce = false

UserInputService.InputBegan:Connect(function(Input , IsTyping)
    if not IsTyping then
        if not debounce then

            debounce = true

            if Input.KeyCode == Enum.KeyCode.E then
                game.ReplicatedStorage.FireBall:FireServer()
            end

            wait(1)
            debounce = false
        end
    end
end)
