What would change? Gonna pack your bags and travel a few thousand lightyears to say hello to some civilization that most likely doesn't exist anymore?

Well, I think a lot would change actually. On an emotional level there would be worldwide astonishment despite however many already "believe" The more tangible evidence that comes our way the more tangible our amazement becomes. The amazement is more of recognizing how incongruent our former belief systems were in general - simply, not being alone.

From there however comes the real turning point imo. Something of that nature, whenever we reach communication that is, would give people a more long-term vision of life on Earth and in space. The exact kind of long-term thinking necessary for taking actionable steps to secure the health of this organism we call Earth.

Denial of Gloabl Warming, imo, is not really about religious nuts so much as it is about a short-term thinking mentality that we have yet to rid ourselves of biologically. It was necessary in the Cave-age, but now no longer.

This! This is very important. There will be countless amount of things that will change and will need to be changed if humanity wants to have a future not just in the universe, but sustainable here on Earth. For example a lot of currant "points of view" will no longer become a matter of debate. There will come a point where we can no longer isolate ourselves. Once we leave our planet, we are in a domain of a greater community. As far as our planet goes. We may one day need aid, or to expand/leave when Earth becomes inhabitable. And yes, we will likely be required to have a one world government or a World Council to represent out people in the post contact world for a long list of reasons that could prove to become disastrous.

The short term mentality is going to cause a lot of issues. Currently it's already preventing us from making leaps in human advancements and tackling issues we already have here on Earth. Imagine what will happen when the whole world becomes aware of this reality should it be the case?
