Egyptian antiquities officials have announced the discovery of at least 100 ancient coffins, some with mummies inside, and around 40 gilded statues in a vast Pharaonic necropolis south of Cairo. https://amp.abc.net.au/article/12884648 Either an amazing or a grizzly find, depending on how you look at these things!
Not sure what you find fascinating about. You should go to a graveyard and dig up some Graves for a really good time.
Each person has their own taste and interest but for many Saqqara is a marvelous site. It was created about 4500 years ago. I last visited the site over 10 years ago. It contains some of the earliest intact buildings in human history. The step pyramid of Djoser supposedly predates the great pyramids of Giza. The Teti pyramid had walls and ceilings engraved with writings and decorations something you see none of in the great pyramids. Those coffins they found will help us to understand more about how they treated the dead and hopefully a bit more about how they lived.
Depends on the circumstances. People study fresh corpses for medical research all the time. Skeletal remains can answer many questions about cultures ancient or otherwise. I guess the answer to your question is if it can help us unveil some outstanding questions then it is worth studying. I remember recently they found the remains of King Richard III in a parking lot. Since then the remains have revealed a lot about his supposed hunchback conditions and health in life. Everything from his ability to wear armor and wield a weapon to what foods he ate.
I see no problem studying history and archaeology. At least we can learn from history. I don't know what is the practical value of archaeology, however.
I find that visiting these sites and seeing it, connecting with locals creates a more tangible experience. I suppose the practical outcome is expansion of consciousness.
Definitely worth the effort to visit sites like this. Also there is nothing wrong with knowledge for the sake of knowledge.
