What is the Fermi Paradox? (Where are they all?) Fermi's paradox came as a result of existence of a physicist called Enrico Fermi. It refers to the difference occurring between arguments of scale and probability that intelligent life in the universe is privileged and the failure of evidence on whether intelligent life exist on earth and on anywhere else.

It is clearly portrayed by Drake equation as it tries to explain the existence of other elements in the universe apart from the earth.
The Milky Way
In our galaxy, we have billions of stars which resemble the sun but they existed a thousand decades before the earth. Just like the earth, these stars have planets which may be intelligent later. As a result, the earth is expected to should have experienced extraterrestrial aliens but prove has been put forward satisfactorily.
The Fermi paradox at first stresses so much on the part of the large scale used. The numbers of stars found in the Milky Way are between 200-400 billion and 70 sextillions all over the world.
To some extent, few planets in the stars have intelligent life but there may be other elements even in the Milky Way. Thus a fallacy that the earth is a planet of its own arises. Another prospect of the Fermi paradox is the controversy of probability. In a case where intelligent life is capable of subduing shortages and manipulate new environment, some civilizations would have undergone an immense civilization.

How Old Is Our Universe?
After 13.8 billion years, there is no manifestation of an intelligent life everywhere in the universe. Therefore, a convincing answer has to be found regarding this conflict.
Some of these answers are that our thinking on intelligent life if bigger than the normal. Also, there is partial comprehension of the scientific nature. Fermi paradox can be presented in two modes: the reasons for the absence of artifacts or aliens in the earth and even in the solar system. Secondly, lack of any intelligence elsewhere in the universe. This incorporates other galaxies. However, Fermi paradox has some criticisms for the logic it suggests.
