There isn't really an official discovery date for the moon. Ever since humans have been here, the moon's been here, too. And it wasn't hard to see.
Earth's moon would have been the first moon discovered. Galileo observations identified four of Jupiter's moons - Io, Europa, Ganymede, Callisto - in 1610.
in the earth, people discovered
the first moon discovered on Saturn is Aegaeon
The moon has been visible in the sky since ancient times, so it was not "discovered" in the traditional sense. Human civilizations have always been aware of the moon's presence in the night sky through observation. The understanding of the moon as a celestial body orbiting Earth has evolved over centuries through scientific observation and study.
The name of the Earths moon is, Moon. A name was not given to the moon at the time it was discovered because no one knew that there were other moons.

One natural satellite of earth so far discovered.
no one discovered the moon...you can see it from anywhere on earth (just about)
The moon has been known since the first primitive man looked into the night sky. It certainly pre-dates history and any calendar
What was discovered was that the moon is composed of material that is very close to the composition of the outer layers of the earth. A theory has been adopted that the earth was struck by a small proto-planet, about the size of Mars, and the collision threw much of the earth's crust into orbit, that eventually formed the moon.
Io - a moon of Jupiter
Humans discovered the moon the first time they looked up at night. Animals discovered it earlier.
