If you think evolution is fictional, I suggest you talk to whomever is in charge of infection control at your local hospital. :-)
That’s a red herring. Bacteria and viruses aren’t evolving into a different kind of creature, now are they? They’re merely reordering their existing genetic information in response to external stimuli, such as attacks by antibacterial or antiviral drugs. The information, or programming, is already existent inside the organism. They aren’t somehow developing new genetic information.
