One of the most silly arguments that Ahmadis make in terms of the tomb of Esa (As) is that Esa (as) somehow lived 90 additional years after the attempted crucifixtion.  Ahmadis use silly arguments that are given to them by their mullahs, and they never double check the content.

MGA and his team used Nicholas Notovitch’s fake research work
As we all know, in roughly 1896, MGA and his team landed on the idea that Esa (As) was buried in India.  A few years later, they connected it with the tomb of Yuz Asaf.  Then they made up false reports and relied on shoddy information to seal their idea that Esa (as) died in Kashmir.  However, research proves to us that Nicholas Notovitch actually lied about all of work on Jesus in India, thus, the foundation of the Ahmadiyya belief that Esa (As) =Yuz Asaf is a total lie.

“Faced with this cross-examination, Notovich confessed to fabricating his evidence.”
