THIS!
Life is a concept so hard to grasp, the line is so blurry that, like you said, why is a single cell bacteria alive but a virus is not? Viruses do all the things bacterias do except reproduces with it's own means because it lacks the resources so it takes it from others, you could say is a parasitic, but you can see parasitic wasps in the wild a tell that they are very much alive, but they need something else from another animal to reproduce.

That's in the micro sense, what about the macro? Why are not societies alive? Societies are a system very much like ourselves, a circulatory system like highways, factories like the liver.

This is something to think for decades? Is humanity alive? AND WHAT'S UP WITH VIRUSES AGAIN?

Amazing post man! I really enjoy it!
