any chemical reaction that occurs in the human body can be reproduced in a lab.
so before some nobel prize winner takes my credit i want to say.
There is nothing in organiisms that cannot be reproduced by lab experiments.
i have alot of respect for religous people, but the reality sidetracks from the former ideals somewhat.
All i can say is that if you ask as a true physicist such as einstein if we are specieal he wouuld say no.
the reason is that everything, and i do mean everything, that happens in human mnds and brains, is subject to the laws of physicis.
in other words, we should not fear death, because the idea that we are "alive" in the first place is and ignorant one.
so in conclusion, you should not fear death, because, death represents the end of life.
But if you really, really understand life, and what we are, then, you will understand that our illusion of being alive is short sighted.
our immortality depends on what the universe has in store for us
