Does it really originated in China?
I read on a news website that it was created in lab (any other country) then it was brought to wuhan and people got infected in wuhan...Yes. That exactly what happened.

I think here it responds to your questions about the origin. Simply coronaviruses exist naturally. However this one, had the genetically engineered mutation of targeting the ACE-2 interface in human cells.
You can see it by the fact that it's only know that this unstable virus start to creep on other species (minks in Danemark), rather than highly pathogenic avian influenza (HPAI being present in all birds first then humans, or those H1N1 swine flue which jump from pig to human.
Here we see the reverse, the C19 jumps to animal.
You have premise, that it wasn't intentional...
I understand that for some people it's hard to imagine that others humans would have evillike intentions... Sadly, history has proven that it being more the norm than the exception.

This is one being a famous example.
So wouldn't it make sense to shut down the greatest american economic revival ever by the current President (Trump) using a virus? To then foster the so-called "great reset"? In short, read my sig.
If it doesn't make sense to you... maybe it's that you are too kind...
