In a bioweapons lab.

Corona virus can't and didn't cross the species barrier.
There are three different types of coronavirus. One type infects only animal species (dogs, cats, other warm-blooded animals). One type infects only bird species. One type infects only human species. The different types can't "cross" species.
If your dog catches a virus, your dog can't pass it on to you. If you catch a virus, you can't pass it on to your dog.

Working in wet markets with wild fresh meat and not washing hands would do it.

Random mutation occured in a location where there is close contact between humans and live wild animals.
Had this same mutation occurred somewhere far from humans it would probably just die out.

Actually, it is not exactly known how it crossed, and how it mutates they way it does. It is a bit of a mystery. Google is good, but it does not contain all the answers.

Coronavirus originated in people working in a fish market in Luhan, China. It was always a human disease.

Humans ate infected wild animals in China. They have what's called wet markets where they have live wild animals and they slaughter them for you if you buy them for meat. People walk through the blood and the tables are full of mixed animal blood. It's a horrific thing.

Apparently this virus is more contagious than we've been told.
