" #SarsCov2 has never been isolated" strikes me as arguably the most absurd of all the ' #COVID19 myths', and this in the face of stiff competition on all sides of the debate. I'll answer one last time and then I give up ...

#SARSCoV2 has been photographed many times with electron microscopy. As all coronaviruses it is spiky, hence its name (corona in latin = crown).
e.g. https://www.nature.com/articles/d41586-020-00154-w?sf229468909=1

A very large number of lab animals have been experimentally infected with #SARSCoV2 which resulted in measurable symptoms often similar to those in humans.

Hundreds of thousands of #SARSCoV2 whole genomes have been sequenced. There are ~262k whole genome sequences from all over the world stored at this stage on the genomic data repository @GISAID ( https://www.gisaid.org ).

The genomes make perfect sense when analysed computationally. Strains transmitted between people cluster, and one can use the genomic data to estimate the time when it jumped into humans (late 2019) and reconstruct its spread during the pandemic.

There is no other virus or other microorganism for which we have as much evidence for its existence than #SARSCoV2, none ...
