Subsequently, question is, what is a constellation as astronomers define it today? Constellations are groups of stars that humans perceive as forming a pattern.

Imaginary sphere with the stars embedded on it. Pair of quantities right ascension and declination similar to longitude and latitude on Earth, used to pinpoint locations of objects on the celestial sphere.
Do constellations have a purpose?
The real purpose for the constellations is to help us tell which stars are which, nothing more. On a really dark night, you can see about 1000 to 1500 stars. Trying to tell which is which is hard. The constellations help by breaking up the sky into more managable bits.
