Covid-19 is zoonotic in origin. That means it was active in animals before it was transmitted to humans. There has as far as evidence has found so far been no genetic engineering. The evidence points towards it being transmitted to a person from one of the live animal markets in Wuhan, naturally animal to human, not a lab.
Beyond that and locating the original animal source, it doesn't matter a flying fudge how/who was involved in it starting. Right now the important thing is how we as a
global population respond to and pull down this new pathogen.
The only thing pointing fingers and making unsubstantiated claims does is effect the global populations ability to deal with the crisis because fear and mistrust slows responses and crumbles cooperation. If you blame the town twice over of setting a fire to your hey barn, how likely are they to come help douse the flames if it reaches the steel-mill 90% of your town work at?
People are being beaten in the streets just because of their appearance and fear of what is unknown and what, right now, cannot be known. Don't be the guy that climbs to the second story of a house to get a better look at how the Tornado started when he should be helping everyone else in the family batten down the hatches and getting into the cellar.
There will be time for theories later. Right now help, don't hinder.
