So if we would calculate the probability to meet intelligent civilization on the Earth-type planet, what is in the habitable zone of the star, we could find number 100. So in every earth type planet, what orbits the star in the habitable zone should have an intelligent life form. And here we must ask again where are those civilizations? When we are looking at the Drake equation, we must think about the question, where are the aliens, if every earth-type planet in the habitable zone of stars would have intelligent life. Here we must go to the Fermi paradox, the attempt to explain why there would be no answer from another civilization? The one thin...
