"However, if all the human diseases were carried on the Ark, Noah and his family would have never survived."

Obviously. Genetic diseases are the result of mutations after the ark. We know mutations occur. Bacterial infections are the result of bacteria. They obviously survived. I'm not sure where viruses came from. They may come from decaying life. They may have survived the flood, or they may have been created or occured afterwards.

What does evolution say about viruses? Are they common descent too?

Danny, if there are mutations, that means that God did not create us perfectly. That goes against the literalist view.

You are not being consistent and you are not being intellectually honest. It is impossible to discuss this with someone who twists and turns like a snake down a sewer.

I don't know. What does the Bible say about viruses?
