A few hundred years ago some astronomers where proving that the earth goes around the sun and we are not at the center of the universe, many people didn't like this, but why? The reason is because deep down inside the ego didn't want to hear it, it wanted to continue believing we are truly important and special. It's the same reason people buy a bigger house or car than their neighbors- to feed their ego even if it is an illusion they still need it, but how much of the world is clouded by our ego and emotions are hinden motives? Is it such a bad thing? Does anyone want to add to this? Lets suppose aliens exist, the universe is infinite and been going on forever and gives rise to self-aware beings, then there must be civilizations vastly superior to ours, so much so that our planet is a hole in the backyard, our technology our understanding and ability to think are all incredibly worthless by comparison and insignificant, would anyone want to believe this? What is to be gained in seeing it this way?
