Although I think it would be great if extraterrestrials introduced technology that would enable us to leave this rapidly screwed-up planet and relocate to a new world elsewhere in the galaxy, chances are it won't happen anytime soon given the immense distances of interstellar and intergalactic space and we will be left alone. Even if aliens have discovered Earth recently either through our radio and TV transmissions or by exploration, or came in the distant past, it's possible they have some type of non-interference directive or philosophy to let us and similar worlds progress on their own. If any hostile alien species discovered us, you'd think they would have conquered or destroyed us by now. So we will probably have to wait and get out there on our own assuming we don't self-destruct before reaching that technological level.
