No no, it's good for atheists to call each other out. We operate with logic. But sometimes dry logic is hard for people to chew. You need to add some sauce in there.
It's not my fault if this looks silly but I am making a serious point. And I know some Christians believe this stuff because I sure did. Well, of course, I never phrased my beliefs like this, but I did believe in intelligent design. And unlike Hugh Ross, I didn't believe death existed before the exile from Eden. So I wouldn't have had an answer for how precisely viruses existed.
If you look at my avatar, it is a bacteriophage with a lightbulb replacing the genetic material. This is the type of virus that attacks bacteria. It is a wild over-generalization to say bacteriophages are good or bad because bacteria can be harmful or helpful to humans. Furthermore, when we speak casually of viruses, we typically are referring to a coronavirus. Not the coronavirus Covid-19, but just that virus type. That's the type that typically infects animals. What good do they do for us? How do they exist in a young-earth creationist worldview? Keep in mind that Hugh Ross is not a young-earth creationist, which means he's more or less obligated to deny the doctrine of a deathless initial state of creation, which is why I was ignoring him this whole time.
Hugh Ross has odd beliefs even for Christians. Watch his debate with Kent Hovind. Ross contends that animals - he uses whales as an example - have gone extinct and were then created again by God. Presumably this occurred during one of the "day-ages" of creation. I find this whole game to be stupid. Just go with the literal text of the bible or go with science and justify your faith after the fact. I find Hugh Ross to be incredibly arrogant and insufferable in that he insists that his discipline (astronomy) be taken seriously while denying another scientific discipline (evolution). Seriously, watch that debate with him and Hovind and see him losing interest in what Hovind has to say about astronomy because he knows for a fact that Hovind is wrong, since he has a PhD in astronomy, and then he casually goes on to deny evolution. Hello! Does he not know how he's doing the same thing? Those of us who attended universities and acquired acute knowledge in certain fields are supposed to have learned to respect those in the other fields just as you expect them to respect your expertise, and he is disrespectful of academia on a daily basis.
