Seems researchers found low levels of SARS-COV2 RNA in frozen Barcelona wastewater samples from March of 2019. Apparently there were several serious "flu" cases there around that time, which may have actually been Covid-19 cases. This pretty much blows up the "China Virus" theory. Instead it might be The Spanish Virus. The reason they first noticed it in Wuhan might simply be because they had a decent virology lab there!
Researchers have been studying Spanish bats for a long time. They do carry corona viruses, and are thought to be the possible original carriers of both SARS and MERS. They actually harbor a lot of viruses: Like rabies, dengue, hantavirus, yellow fever, Japanese encephalitis, and West Nile.
The intermediate animal might have been a domestic cat, since they are know to catch bats, kill, and eat them and are also known to be infected by the SARS-COV2 virus.
We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
