I look at it this way
We know that the human body is full of energy, both chemical and electrical.
The first law of thermodynamics is that energy can neither be created or destroyed.
So when the human body dies, the energy has lost it's housing. It has to go somewhere else. That's plain scientific fact.
Also,
There have been countless testimonials by people who have had someone die in their arms stating that they felt something leave the body. That they could no longer feel the essence of what was that person. Call it an energy force, life force or soul, something leaves us when we die.
I've had 3 extrordinary incidents happen to me (all while hallucinagenic-drug free, I might add) that lead me to believe in old souls. I won't go into it, but it was enough evidence to prove the case to me.
