Yes..it's definitely true...as Moby says 'we are all made of stars'...I'm not the expert on this, we need...well, everybody else really !!..but it is indeed true, the building blocks of eveything that you know commenced inside a stellar cloud where a star was born....

ok...someone please take over for the Science.

The initial processes in the big bang produced mostly hydrogen some helium and a trace of duterium helium three and lithium.  that is the first three elements in the periodic table.  the resdon for this is the densiuty was relatively low when these elements were formed and the time avaliable as the universe expanded through this phase was relatively short.

The important elements for life carbon, nitrogen and oxygen with traces of elements all the way through the periodic table required stars to have formed, Created the higher elements in their cores furing the fusion process.  blown themselves up and dispersed the elements that they created into space.

but it doesn't take very long  heavy stars arouind ten to a hundred times the mas of the sun only last a few million years before they burn themselves out  compared with the ten thousand million year life of a star like the sun.

Learn, create, test and tell
evolution rules in all things
God says so!
