Nobody made Halley's Comet, and there isn't any purpose to its existence. It simply is.
The comet is kept in orbit around the sun by the gravitational pull between the comet and the sun. This gravitational force acts as a centripetal force, keeping the comet moving in its elliptical orbit.
Halley's Comet is currently a little beyond the orbit of Neptune.
