Humanity.

 There is no way to light a lamp without burning it again!

 He in whom humanity has disappeared, can give nothing but darkness like an oilless lamp!  But if the seeds of humanity can be sown in it, then maybe some light can be radiated!  However, the bright light will never spread like before!  Lamp oil can be bought from the market, but humanity is not available to buy!  It takes a lot of time to achieve!  Minutes are enough to be dehumanized, but it can take ages to recover!
