The hypothesis of one version of alien civilization: a two-floor society where one alien species works as "servant" to another alien species.

The hypothesis of one version of alien civilization: a two-floor society where one alien species works as "servant" to another alien species. 

This is writing in the theoretical possibility that sometimes in the future we could land on the planet, where is another intelligent species. There is one very interesting scenario about the possibility, that the hypothetical alien civilization would consist of two species. The "master aliens", what will give orders and the "slave aliens", what mission is to serve their masters.

One of the best possibilities to control other species is to manipulate themselves to keep their IQ extremely low. In that case, the controller of the system would need to say everything, what those creatures will make because they don't have abilities to make anything against their masters, and the role of those hypothetical workers be the machines, what is following every rule what other people will say to them.

There have been scenarios, that we would someday meet so-called stupid aliens. Those aliens would have extremely low IQ, and that kind of situation would be very interesting because we would be the superior species in that kind of case. If we would face the hypothetical alien civilization, what members are in the level of gorillas we must realize one thing. The environment, where those aliens would live means everything in that kind of case.

And the worst possible case would be the "cities of monkeys". If those aliens would have low IQ, but they have things like cities and other kinds of things, we must ask who controls those aliens? That control can be made by using implants or simply sound, and this kind of hypothetical situation can mean that those dumb aliens would have some kind of controller, what is another civilization, what is above those aliens, what mission is to obey that kind of thing.

In this scenario, another alien control other aliens, and that kind of situation would be scary. There must be some kind of reason, why some aliens will make the entire species their servants. And if the controllers would not show themselves that kind of situation is alarming.

If we are thinking about the possibility to face the post-apocalyptic civilization, what has risen from the ash of some other species, that kind of situation must be seen on that hypothetical planet. There should be some kind of marks like ruins of the destroyed civilization. But what if those ruins do not exist, but the entire planet would be full of marks of ancient civilization?

The question would be, "why those members of master species have destroyed the proves of their existence so carefully"? Why they would want to hide their existence? This kind of question might be in the head of the hypothetical spacecraft crew, which might face this kind of situation in the distant future.
