.

There is no way to date the bacteria and viruses in the same way. 

But I can say that bacteria is the first one to came than viruses, some of the first organisms was cyanobacteria, a bacteria! 

Viruses did not evolve first, they found. Instead, viruses and bacteria both descended from an ancient cellular life form. But while – like humans – bacteria evolved to become more complex, viruses became simpler.
