Question

if de == true then
    print("we found a human!")

end

end)

is not working?? I'm new to this but i just don't understand!

Answer 1

The reason why your script is not functioning as intended is because :FindFirstChild() will return an object. (not a boolean)

So your statement is practically stating

local part = Instance.new("Part")
if part == true then -- Part does not equal true

The solution is quite simple. When :FindFirstChild() doesn't find anything it will return nil. So just make sure that it `~=~ nil

local find = script.Parent    
find.Touched:Connect(function(touched)
    local de = touched.Parent:FindFirstChild("Humanoid")
    if de ~= nil then -- checking if a humanoid was found
        print("we found a human!")
    end
end)

Answer 2

If you are trying to detect if a player was joined then Try use this code:

local find = game:GetService("Players")

find.PlayerAdded:Connect(function ()
    print("we found a human")
end)

Copy it into your LocalScript and place your LocalScript in StarterGui library
