Is it likely that elements 119 and 120 already exist from some astronomical event?

I learned recently that elements 119 and 120 are being attempted by a few teams around the world. Is it possible these elements have already existed in the universe due to some high energy event and if so is there a way we could observe yet to be created (on earth) elements?

Such heavy elemements are extremely unstable. Therefore they decay in fractions of a second after they are created. Even if they are created somewhere outside of the earth, there is no way that they make it to earth and then stay intact long enough for us to identify them.
