Do ALIENS exist really?
You mean intelligent life elsewhere than on Earth: The correct answer is “we do not know”. We have no proof that they exist. We have no proof that they do not exist. All we have is a statistical analysis: if the universe is very large, then the probability of aliens NOT existing is small. The larger the volume we analyze, the smaller the probability that they do NOT exist. If we consider an infinite universe, then the probability of aliens NOT existing tends to 0%. This would mean that the probability of aliens existing, tends to 100% in an infinite universe. But we do not know that the universe is infinite.
Good question! If people believe that we are the only living creatures who live in the entire universe, Than I do believe they are wrong. The universe is too huge to even think we are the only ones but, being it is so large, the travel time and all the elements in the universe prohibit anyone to travel that kind of distance to even arrive he. We have the capability to see billions of light years away and have not found a single planet to sustain life as we know it. Therefore it would take a literally a million years to travel to the next area to find another planet capable to sustain life. It takes 75,000 years alone just to get to the next galaxy closest to us. Your belief of aliens or not, is as good as the next person. The choice is yours.
