Strange that China as the source is still accepted. Wuhan outbreak was in Dec 2019, everybody remember?
Here are the actual studies, see for yourself. No opinion. Just findings.

SARS-CoV-2 RBD-specific antibodies were detected in 111 of 959 (11.6%) individuals, starting from September 2019 (14%), with a cluster of positive cases (>30%) in the second week of February 2020 and the highest number (53.2%) in Lombardy. This study shows an unexpected very early circulation of SARS-CoV-2 among asymptomatic individuals in Italy several months before the first patient was identified, and clarifies the onset and spread of the coronavirus disease 2019 (COVID-19) pandemic. Finding SARS-CoV-2 antibodies in asymptomatic people before the COVID-19 outbreak in Italy may reshape the history of pandemic.
It's not a "China virus". It was spreading globally
before the Wuhan outbreak. September comes before December.
The COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a rapidly emerging pandemic which has enforced extreme containment measures worldwide. In the absence of a vaccine or efficient treatment, ...

Here, we have used RT-qPCR for SARS-CoV-2 detection in a series of longitudinal metropolitan wastewaters samples collected from February to April 2020, during the earliest stages of the epidemic in the Region of Valencia, Spain. We were able to consistently detect SARS-CoV-2 RNA in samples taken in late February, when communicated cases in that region were only incipient.
In Spain, it is found in sewerage before the outbreak there got started. Widespread incidence, flying under the radar.
Similarly in Brazil
Human sewage from Florianopolis (Santa Catarina, Brazil) was analyzed for severe acute respiratory syndrome coronavirus-2 (SARS-CoV2) from October 201…

Our findings demonstrate that SARS-CoV-2 was circulating unnoticed in in Brazil since Nov 2019
At best, it is unclear exactly where this originated, but there's no reason to assume it was Wuhan, or even in China. After Wuhan was locked down, the rest of China did not erupt in disease, because there was no widespread disease.
Or it would look like India now.
It simply could be that Wuhan imported it. Or that it mutated there.
There is some controversy about similar US findings dating to Dec 2019.
SARS-CoV-2 antibodies detected in blood donor samples indicate infections could have occurred in the US more than a month before the first confirmed case, but some experts remain skeptical.

Don't be misled by racist nonsense, we have really had enough of that. If we adhere to verifiable information, we get a much more accurate picture.
