It's the year 3105, almost 50 years have passed since the Great War. No one wants to talk about it because they say it was the most horrible and devastating war in history. People no longer live on Earth, it's completely destroyed and burned by pollution and by radiation from the Sun's rays. Now the Earth is inhabited by humanoid androids.
Soon after the end of the Great War it was decided to create human androids to avoid the extinction of the human being. On Earth there are only 3 zones that are still habitable; and in one of them the androids live. They have never gone abroad.
All androids live at the Center. They are separated into men and women and have never seen each other. That is, men have never seen women and vice versa. They all are physically equal and wear compulsory white.
They only know the 20 persons they see every day. Which are scientists who test them every day. And they have everything calculated. Each of the humanoids blinks exactly 53472 times a day and they have 203566 hairs on their heads.
In the first habitable zone of the Earth there is a complex laboratory from which robots are sent to examine the most destroyed areas of the Earth. These are responsible for finding some trace of human life.
They have a cemetery although they never die. They built it as a reminder to humans, to remember them. That tombs are empty. It's a symbolic memory.
