If I am not mistaken, accordingly to the Big Bang theory, all particules were created at the same time. Not before or after, or few of them but all of them at the same time.
No new electrons/quarks/… were created since then.
Photons are an exception (at least, in as much as that they are a particle), and you can make new particls from energy, but definitely there’s a limit to how old a particle can be. No particle is older than the universe (as far as the big bang is concerned).
