A year ago I was given as proof that covid-19 exists that "you can even see pictures of it [online]," so it then must be real (I mean, people have pictures of "bigfoot" and whatnot, as well).
So, if you go online and look for pictures, all of them are CGI... And they all also look different from each other, calling into question if they really all are of the same particle (which also has never been isolated or purified). Look it up, and you'll see what I mean (that they are all CGI and all look different from each other).
A proof given often that the earth is a sphere is that you can see "photos" online of the ball earth.
They're ALSO all CGI and different from each other!
