I think many are looking at it the wrong way.
If you think you are no more than matter(your body) than you are not immortal.
But when you find the energy part of you, which in reality is you, you are immortal and can then go on to meet those who have long left this 3rd plane and are out there in another plane of the universe.
Everybody agrees we are all star stuff, but forgets star stuff is not just matter, it is a constant changing of energy to matter and back.
