Out of all those advanced civilizations in the universe, what fraction use electromagnetic radiation for communication? We are like ants waiting for other civilizations to communicate with us using pheromones.
There are humans that try to talk with ants (and bees, and dolphins) using those creatures' own methods. Unless there were strongly-enforced no-contact laws, then some alien researcher would want to inspect those Terrans and see if we can talk. Even if they are way smarter, they'll use that smarts to talk with us in a way we can understand.
