“If you took the culture materials from that dish (the one with no human material) and looked at it under a microscope, you would also see degradation break down particles, and you could pick one in there that you could call a virus.”
“There’s no virus (material from a human) in this experiment”, but the experiment produces the same results that virologists use to “isolate” and prove the existence of a virus.
Translation: WHAT VIROLOGISTS CALL A “VIRUS” CAN BE PRODUCED WITHOUT ANY MATERIAL FROM A HUMAN, SICK OR OTHERWISE.
