Bacteria have been shown to exist you can see them under a microscope they can be cultured and grown ...viruses.. well maybe not, if you go back and look at the original "research" they took spinal tissue from "infected" patients and injected it into monkey brains who then subsequently died....therefore proving that the "virus" causes death ?
There is more but you can think about it a bit and find some debunking material from Google if you want.
