Viruses are living parasites that enter a living cell and use the genetic material in that cell to reproduce itself. If one claims that the full definition of life requires the organism to be totally self-sustaining and self-reproducing, then viruses are not truly 'fully' live.

(Or the beginning as it were.)-You are simply raising the same issues we all have. We know many of the secrets of life today. No one knows how we got to this point. Starting in a less complex fashion is a reasonable proposition, but it hasn't worked so far in the labs, starting in the mid-1950's.
