The stars (or star) that birthed the elements from which the solar system is built are long dead in supernovae.
The process of nucleosynthesis within those stars means that they didn't have the same chemical abundances, either.
The supernovae that blew those stars apart, spreading their elements also created most of those new elements.
Not only that but our galaxy is in rotation and has interacted with nearby galaxies, so even the identification of where those stars might once have
been is unclear.
