How were those first stars formed?

Nebulas formed after the Big Bang are vastly known as the home of stars. The gas and dust present inside them were in normal state till any object from the outside created any disturbance. Any object from space that passed near the Nebula or hit that, started movement inside it. These huge movements which were caused by the gravitational force bended the space-time and the gas and dust inside it started to be attracted at a single point. They were attracted till they make up a huge mass like that of Sun or even 100 times bigger than it. This process took millions of years itself. Since it was gaining energy it's temperature kept rising and it became a Pre-stellar core. When the temperature is 1000°k the process of Hydrogen fusion started. And thereafter the Pre-stellar core evolved into a Star.
