That´s why we are doomed, when aliens visit us.
They even won´t understand what a border is.
We still think inside our box and won´t be able to change that.
That´s a pitty but it´s a fact...
Maybe in 50 or 200 years the world will try to stick together for the rescue of mankind...
But to be honest... I don´t think that will happen....
I think we're the last place aliens would come to visit us to be honest, they're probably laughing at us in another parallel Universe like soe kind of reality TV show!
Hmmm not so sure about that.
We´re in a quite comfortable zone in our solar system.
The habitable zone is a rare state in the universe and could definitley attract other species.
We got everything you need: Water, Air, Humus, Day/Night cycle, mild temperatures.
And that´s why I would visit the small blue planet.
But you are right with the point, that they would laugh about us.
They even won´t understand what we are doing.
It could be like you and me, staring at an anthill ;-)
