I know how it all works, but it’s just somewhat weird. Some of the posts in this thread are about houses, but they are made up of other things, sometimes older, like bricks. They don’t consider those though. If the OP here used his meteorite as a piece of his house, would he no longer consider it the oldest thing he owns? It’s a ship of Theseus. Why does it change when it’s part of something else? (Rhetorical question.)
