If I had a time machine and could follow just one piece of these artifacts... what an incredible trip that would be. It would also answer the question “How in the heck did these wind up at the bottom of the Nile?”. Didn’t they have a Goodwill Store back then, when cleaning out the palace?
Most personal possessions went into the tomb. Even Tut’s smallish tomb was stuffed with all kinds of things, including a chariot. :^) The temples were built to last, but the palaces all went away for the most part, mud brick with some kind of painted plaster coating. That was intentional.
