How are stars created? Do stars last forever?

1. They are born from other stars.  They do not last forever.  They last until they have a baby.
2. A star starts as a cloud of mostly hydrogen and a little helium and some heavier things.  It collapses and gets hotter.  Hydrogen is turned into helium by nuclear fusion.  And then you have a star.  Stars do not last forever.  They start to break down recycling to make new stars.
