Its not at all. see the docu on Netflix "Understanding Corona virus"
Labs often make virus in a controlled environment so if they eventually hop from animal to human we have years head-start on a vaccine etc.
The Wuhan lab had it. somehow it got out.
dr LI that first alerted ppl in Wuhan about it called it "sars2" It has 96% the same DNA as Sars1.
Had the Chinese government taken heed to Dr Li instead of putting him in jail, the docu said that 95% of the cases could have never happened
China made him sign an affidavit that he was a "liar" and "fearmonger"
They actually showed the summons.
Dr Li died of the virus a week or 2 later
