It could be. But that I find extremely unlikely

A failed experiment? Maybe a bit more likely, but still I don't think so

Sars-Cov-2 looks like pretty much what it is: a zoonotic virus that "doesn't know what's going on"

Hence why only the recent mutations made its transmission more efficient.

Now, if it escaped unbeknownst from a research lab, that I would put on the plausible category. Would be more possible if it wouldn't have had a perfect virus breeding ground right next to it.

How about this possibility: (1) You've got this lab that uses a lot of animals and does experiments. (2) There is a 'wet' market nearby that deals in animals from A to Z. (3) Maybe some animal from the lab carrying a zoonotic virus (origin unknown) somehow got disposed of for cash in the market? How could WHO or anyone uncover such an occurrence a year or more later? Would it be possible that such a thing had happened and no one ever had had any idea that it had happened?

Yes there are several possibilities. And no, I don't think anybody could figure something like that out.

What you can do is follow chains of mutations and infections and try to get somewhere.

It was actually remarkably stable in the early days suggesting it was used to reproducing in human cells. Or so Professor Petrovsky says https://www.dailymail.co.uk/news/article-8356751/How-COVID-1...

As how that could have happened lab wise here's Daszak saying they routinely infect human cells with coronavirus in the lab https://www.youtube.com/watch?t=1701&v=IdYDL_RK--w&feature=y...

Or maybe it was in humans a bit before it took off. I see Daszak's kind of changed his tune a bit these days to not mention anything like that lab stuff.

"Human cells" are mammal cells. Macaques and Golden Hamsters can get sick with Covid-19

The common Flu can infect horses and even chickens. "stability in human cells" means pretty much nothing

>>raverb+Ek
I mean stability in that the sequence of the virus is much the same as it was a month before. That's not true when a virus jumps species - they evolve rapidly to the new species.
