The age of the oldest rocks on Earth & Moon are about 4.5 Gy old. But doesn't the material that made the Earth come from the supernova that had occurred prior to the formation of the Solar System, and doesn't the radioactivity dating measure the age of the creation of that material in that supernova, and not simply when that material had coalesced into the Earth & Moon?
Perhaps the formation of the Solar System was a short time after that supernova, so it would essentially be the same age?
