Planets do not create or "make" anything in the same way that stars produce galaxies or stars give rise to planets. Planets are celestial bodies that orbit around stars, and they are formed from the material left over after the formation of a star.
During the process of star formation, a cloud of gas and dust collapses under its own gravity, leading to the birth of a star. As the star forms, a rotating disk of material called a protoplanetary disk or circumstellar disk also develops around it. Within this disk, small dust particles collide and stick together, gradually growing into larger objects known as planetesimals. Through further collisions and gravitational interactions, these planetesimals can eventually accumulate enough mass to become planets.
So, in summary, planets are formed from the leftover material of a star's formation within the protoplanetary disk. They do not have a direct role in the creation of other astronomical objects like stars or galaxies.
