With all due respect, do you really believe that there are people on planet Earth that "don't believe that COVID exists?" That's just a "straw man" argument. Of course it exists. But just because it exists, that doesn't mean that everything we're being told about how to mitigate it is somehow absolutely true. You can look around you and see that's not so ....
I've never met anyone that "doesn't believe it exists". Look at the data from your own government sources, you don't have to believe me.
