These things exist but are literally invisible because they are smaller than half a wavelength of light. Anything that small will not reflect a light ray so it can't be seen.
Electrons have wavelength that is 100,00 times shorter than the wavelength of normal light so much smaller things like viruses and even atoms can be viewed. There existence can be certified in other ways, but they can also now be viewed
What sort of idiot thinks you can look at a virus on a microscope slide?
Do you think hydrogen is just a myth?
