The universe is 13.7 billion years old. The lifecycle of a star, before it goes nova even once, call it avg 10by. 13.7by-10by=3.7by. That would mean that the Age of any planetary body other than stars, since they are comprised of heavier elements, could not be more than 3.7b years old. Even if they were formed directly from the output of a single Supernova. The earth is estimated 4.6b years old.

Your estimate of 10 BYO for a supernova is totally wrong. Our sun will go 10BYO. If a supernova is 20 times sun size it will burn faster and be gone as an s-n 20 times sooner than 10 BYO. That is your theory is way off base.
