Why Is There Empty Space In Space?

Have you ever wondered why is there so much "empty space" in space if there are no other intelligent beings we can communicate with? If this would be true, the whole universe would be a complete waste since humans will never be able to explore not one percent of it. Also, there is so much evidence about aliens, so many sightings and encounters that it is very hard to disprove them all. If the theory of evolution is taken into consideration, the possibilities of intelligent life forming only on Earth are so small that it is insane to believe that such a small possibility could be true. There are so many facts and evidence of the existence of alien life, that, today, not believing in them is too close-minded.
Besides the universe being so big, it contains an infinite number of possibilities, meaning that there are infinite amount of planets almost identical to earth with the same possibilities of containing intelligent life. To this day, the most Earth-like planet discovered by the Kepler telescope is Kepler 22B. It is a
If all the theory that explains how and why life on Earth was formed, then it can also be applied to any other planet in space. If life intelligent life in fact evolved from things as small as microorganisms, which many scientists have practically confirmed to exist in other planets, then why would those microorganisms not evolve into an intelligent form of life? With so many other planets with the same life supporting characteristics as Earth exist, there has to be at least one that will eventually make those microorganisms evolve into an intelligent form of life. Besides, it would be very hard to assume that Earth was the first planet to evolve intelligent life if there are any other planets with microorganisms in them. This means that by now, multiple planets should be containing intelligent life that we are yet to
