I'm not talking about anything vague.

We have imaged viruses. We have seen how they work. We have grown them, and infectious bacteria, in cultures. We've seen their interactions with other cells.

And when I say we, I mean me, personally, with my own eyes and equipment.

I do not trust studies and papers just because they're from 'scientists'. I replicate experiments.

Is it fair to assume you do not have the same hands on experience?
