Honest question. What's the point? What's the goal? What do we hope to learn or find or achieve, by making contact with or even co-existing with extraterrestrial intelligent life? What problems are we trying to solve?
Are we trying to find out the meaning of life or existence? Are we hoping to find new technologies that allow us to never have to work again? Do we hope for world peace to come from it? Are we trying to solve world hunger?
Do we want to make new friends? Are we lonely? Are we just bored? Did finding out everything humanly possible about Earth (which we haven't yet) already get too boring? Do we think maybe they'll have a cure for disease and death?
The reason why humans search for aliens is to understand their culture so that we can improve on our well being. Aliens can give us an understanding on how to live longer and show us the implications they faced when arriving to their solutions.
