Letter to an Alien

Hi, my name is Alexander and I come from the planet Earth in the Milky Way galaxy. What planet do you come from? How far have you come in terms of technology? Have you traveled to other planets? The humans from Earth have only been on the Moon, but have sent robots to other planets. What language do you speak? You don’t speak English, right? Then why am I even writing this...? This is weird. 

Bye!
