As for Smithsonian's article, I wonder who wrote it. Quote: ..."dangerous pathogens that cause disease, such as the current coronavirus called SARS-CoV-2 causing a worldwide pandemic...". SARS-CoV-2 has never been identified by any lab anywhere in the world. The same goes for all "viruses". NOT EVEN ONE has been isolated. If I remember right, Steve even posted about this.

As for this statement of yours: "Here is a paper about Koch's postulates satisfied for Sars". Maybe you didn't read the article from nih.gov because the title: "Koch's postulates fulfilled for SARS virus" is a flat out lie. Why do I say that? The first line of their text starts out with: "According to Koch's postulates, as modified by Rivers...". NOT SATISFIED FOR KOCH, BUT SATISFIED FOR RIVERS. That is a HUGE difference!

Thank-you for finding me a pic of a bacteriophage. In your opening remark you stated they are viruses. According to MicroBiologyResearch.org they are not. Please search for this article: "Analysis of genetic recombination and the pan-genome of a highly recombinogenic bacteriophage species". Here is the first sentence from that article: "Bacteriophages are the most prevalent biological entities impacting on the ecosystem and are characterized by their extensive diversity". NOT A VIRUS, but a "biological entity".
