Could a virus have been the first life form on earth?

Answer 1

The most basic explanation for this is that a virus cannot reproduce on its own because it is an organism that only reproduces inside other organisms.

A more intricate explanation is that viruses are thought to have originated from plasmids or bacteria and are a relatively complex form of life with a protein coat.

Furthermore, keep in mind that not all definitions regard viruses as a type of life at all.
