Do viruses exist as living organisms?

Natural immunity is the only true immunity. Everything else is an artificial attempt to cheat nature – and nature is never cheated. … If we think we can fool Mother Nature, we are only fooling ourselves. - Dr Raymond Obomsawin, PhD

No doubt that the Germ Theory has been accepted worldwide by generations of scientists as true and as a starting point for their research. But, does the fact that the majority of scientists accept the theory make it the ultimate truth and humans should be treated for diseases according to this theory only? What if there are no real viruses out there that jump from one person to another as the theory claims? If there are viruses in our bodies, what in fact are they, or what could they be?

Andrew Kaufman M.D., a psychiatrist and a broadcaster on YouTube and Bitchute, refutes Jeremy Hammond's interview opining that SARS-CoV-2 has been shown to exist. Point by point, Kaufman debunks Hammond's explanation of how a virus is discovered and answers the above opening questions of this post:

Aajonus Vonderplanitz, who was a nutritionist and food-rights activist, explained that viruses are not a living organisms: He also spoke about the Flu and explained what he thinks it really is:

Covid-19 was never isolated.

The CDC admits that the Covid 19 virus was never isolated(link is external). There is no way to check for the virus to stop the argument or all arguments related to Covid-19's lockdowns, masks, and vaccines.
From the CDC's:

Since no quantified virus isolates of the 2019-nCoV are currently available, assays [diagnostic tests] designed for detection of the 2019-nCoV RNA were tested with characterized stocks of in vitro transcribed full length RNA…Since that is the case, that there are no quantified virus isolates, how can one be sure of what is being determined as COVID-19 is, in fact, COVID-19?
