The meaning of human life, biologically is to pass on genetic information, to reproduce. One can argue that we do this to remain alive/ this is the closet we get to immortality or this is for the survival of the entire human race. That's not the point of this post however.
Point is, that Viruses also reproduce/ pass on their DNA/ RNA yet they are not considered alive. So dead things can also reproduce?
Also, i have heard of theories suggesting that mitochondria, an organelle of bacteria were once living organisms that evolved into a state of death, moving into the modern bacterial cell that we know today, just so it could pass on it's own DNA/ RNA, hence reproducing itself.
Is there much distinction between life and death if any?
Well viruses aren't 'dead' - they are activated when contact with living organisms.
If you think you're already dead, go outside and get run over by a bus (not really though, but hypothetically). You'll see the difference it makes. Well, you won't, but everyone else could then confirm that you were alive and are now dead.
Being alive isn't just to make children so your biological argument for whether we are truly alive is limited to a scientific perspective.
Religion and love can spur life on much more than wanting to procreate imo
I guess you can have a scientific answer or a philosophical answer.
