You say, "...where Jesus is believed to have buried before his resurrection", Sririam.
What Hope said.
If the remains of a body is found, we'll not it's not Jesus's .
As an aside, I'm not comfortable with excavating tombs or pyramids or the like. They are of archeological, and other, interest of course but there is something distasteful about digging up bodies or remains of them unless there is a sound reason, forensics or something of that ilk. When that is necessary, in this country, the police and forensic experts have to apply for special permission and it's done late or early, with no-one else around, out of respect. Yet archeologists can dig anyone up willy nilly because the dead have no relatives still alive to consult! Just my feelings.

Hi, Sweetpea. Disturbing the dead was something of an industry in Egypt! Re-use of coffins, sarcophagus - even mummy wrappings (All three and more in the case of Tutankhamun) was par for the course.
Go to the Theban Royal Mummy Project site and have a look at the contents of KV 35 and DB/TT 320 - both of which contained the royal dead stacked up like Ikea furniture as their own equipment had been 'recycled' by the state.
If the Egyptian state, which so valued the afterlife, were sanguine on the entering of these tombs, we need not be.
End of Geek alert.
As an aside, I'd like this Israeli tomb entered by professional, objective archaeologists with no axe to grinde.
I say I'd like it - but I hold out little hope that it will be the case.
