The life of a Star begins with a cloud of hydrogen collapsing. Alongside hydrogen, helium as well as traces of heavy elements also collapse and the process of collapsing continues till the core become really dense. Once the required level of density is achieved, Hydrogen is converted into Helium through nuclear fusion process. The star continues to collapse further and this causes the formation of Bok Globules. As the temperature rises, there is further contraction and this continues till the point when gravitational force and gas pressure come to a point of homoeostasis and the resultant formation is termed as a star.
