You are wrong. There, isn't that a stupid argument?

If you are going to just state your opinions as fact without actually providing evidence for extraordinary claims then this conversation is pointless.

It is you, sir, who is making extraordinary claims. The very reference you cite states that: "Reinfection with human coronaviruses, including SARS-CoV-2, the virus that causes COVID-19, has been documented."
