For the same reason that the houses in most cities have numbers on them.
It's convenient to be able to describe the location of a place with numbers.
In other words, it's practically indispensable for navigation.
alberuni invented the longitude and latitude of earth.
Every point on Earth has both a longitude and a latitude. And if someone gives you a longitude and a latitude, you can use them to find exactly one point on Earth.

Latitude and longitude are written in degrees to measure angles. The Earth is divided into 360 degrees of longitude and 180 degrees of latitude, with 0 degrees at the equator and the Prime Meridian, respectively. This system allows for precise and universal location coordinates across the globe.
Latitude runs east to west of the earth and longitude lines rubs north to south of the earth.
Once you name a longitude and latitude, you've nailed down a single point on the Earth's surface, and no other point anywhere on Earth can have the same longitude and latitude.
There is no such location. Every point on Earth has a latitude and longitude, otherwise that system wouldn't be much good for navigation.
The Earth is divided into four parts based on the intersections of the equator (latitude) and the prime meridian (longitude). These parts are the Northern Hemisphere, Southern Hemisphere, Eastern Hemisphere, and Western Hemisphere.
Every point on Earth has a longitude and a latitude. The only exceptions arethe north and south poles. Each of them has a latitude and every longitude.
longitude and latitude
Every point on the surface of the earth has latitude and longitude. If the latitude and longitude of a point are given and they're sufficiently accurate, the point can be found within less than an inch, anywhere on earth.
The globe is divided into 360 degrees of longitude and 180 degrees of latitude. Longitude lines run from the North Pole to the South Pole, while latitude lines run parallel to the equator. Together, these divisions help in navigating and identifying locations on Earth.
