Why do modern astronomers continue to use the celestial sphere when they know that stars are not all at the same distance?

For some purposes, especially explaining the apparent motion of the stars, the actual distances are not relevant, so the celestial sphere is still a useful model in such cases.

Many contributions were made by Chinese and Islamic astronomers to modern day astronomy, including the trigonometric methods created to determine the precision of dates, and supernova research.
Why did man study the moon before modern teleschopes?
Primarily for the reason that it was one of the very few celestial bodies that we were able to effectively observe without modern telescopes.
What is the importance of constellations to mankind?
Constellations are of mainly historical importance, as a record of the way in which the human race used to think about the stars. Modern astronomers do not categorize stars according to constellations, since they have more meaningful criteria. Astrologers, of course, continue to attribute vast mystical significance to constellations.

Do you use the heliocentric or geocentric model in mosdern astronomy?
Practical science often bases its calculations on geocentricity. For example, astronomers use the rotating "celestial sphere" to represent the apparent motion of stars, etc in the night sky. But this is just a useful device. Modern astronomy is certainly based on the heliocentric model of our solar system.
