Hipparchus (190-120 BC), was perhaps the greatest of the Greek astronomers who devised a method of locating geographical positions by means of latitudes and longitudes. Also Ptolemy (2nd century A.D.) was a Greek astronomer and mathematician who lived and worked in Egypt. He wrote the book Geographie which charts all the places of the world as known to them at that time. His works , which employed a system of latitudes and longitudes , influenced map-makers for hundreds of years . He was a cartographer and he evolved the science of map-making.
Latitude and longitude was first suggested by the Greek astronomer Hipparcus in about 300 B.C.E.
In 225 B.C.E. the astronomer Eratosthenes widespread the use of the grid system.

The Greek invented latitude and longitude. Someone devised a concept of using a reference system based on the shape of the Earth, with the coordinates (latitude, longitude) expressed as degrees. In the 3rd century BC Erathosthenes proposed a system of latitude and longitude for a map. The following century (2nd century BC) Hipparchus was the first to use the above system to uniquely specify certain places on th Earth.
That is the center of the coordinate system, which uses latitude and longitude.
The whole latitude/longitude system was invented for the purpose of locating places on the surface of the Earth, and that's all it's good for. Even if you would ask "What is the latitude and longitude of the spot on Earth that Canis Major is directly over ?", the answer to that keeps changing, as the stars move across the sky. It would be like asking for the latitude and longitude of the spot that the sun or the moon is directly over.
Clever. That's a lot like asking "Where in my body am I ?" Since the system of latitude and longitude is a system invented for the purpose of describing locations on the surface of the earth, and is uniquely and exhaustively appropriate to that purpose, the complete answer consists of two parts: 1). The world is located at every imaginable and every possible latitude and longitude. 2). Every latitude and longitude is a location somewhere in the world.
The system of latitude and longitude is used to describe the location of points on the surface of the earth. Celestial objects don't have latitude and longitude. There is a similar system defined in the sky. Those coordinates are called Right Ascension and Declination.

Lines of latitude and the lines of longitude.
The system of latitude and longitude coordinates was invented as a means of specifying locations on the earth. Every location on the earth has a unique set of latitude and longitude coordinates, and every possible pair of latitude/longitude numbers you can name is on the earth.Perhaps the best answer to the question is: "All of them."
The system of latitude and longitude was invented to do that, so that everypoint on Earth could have its own unique set of numbers, and could never beconfused with any other point. Something like the address of your housebut better.
Longitude because you needed a chronometer and it hadn't been invented yet.
There is no such location. Every point on Earth has a latitude and longitude, otherwise that system wouldn't be much good for navigation.
