Why does not this script kill other player?

this is my local script

local rep = game:GetService("ReplicatedStorage")

local remote = rep:WaitForChild("RemoteEvent")

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

local mouse = player:GetMouse()



remote:FireServer(mouse)

mouse.Button1Down:connect(function()

if not game:GetService("UserInputService"):IsKeyDown(Enum.KeyCode.T) then return end

if not mouse.Target then return end

mouse.Target.Parent.Humanoid.Health = 0

end)

this is my server script

local rep = game:GetService("ReplicatedStorage")

local remote = rep:WaitForChild("RemoteEvent")



remote.OnServerEvent:Connect(function(player)

print(player.name.." activated")

end)

it doesnt even print anything, why?
