The U.N. has appointed someone to be our first contact with extraterrestrials should we ever be visited by them. I’m pretty sure, though, if something important like that happened, we’d keep the U.N. far away from it as possible as we do all other important things.
U.N.: “Aliens have landed! We need to talk to them!”
US: “But look what I found here: A paddle ball game for you to play with.”
U.N.: “Yay! Paddle ball! Hee hee hee!”
Of course, the best way to handle alien contact would be to tell the aliens, “Just go in here to talk to our leader,” and as soon as they go in the room they find it’s actually full of angry badgers and we locked the door behind them. Then we steal their spaceships and sell them at our galaxy’s nearest spaceship dealer for space gold. Who knows what’s out there in the universe; better have lots of space gold just in case.
