It is difficult to prove that Sars-CoV-2 was created in a lab, let alone spread on purpose (as opposed to crass negligence of the Chinese commies).
The virus is a chimera of two natural viruses, the kind of which has been created in a lab many times. But it can also occur naturally, if a host is
at the same time infected with both viruses. However, it would be very unlikely, that a Chinese man or woman, was at the same time infected with
two viruses, naturally found in nature, a couple hundreds of kilometers from each other. It's more likely it escaped from a lab, but the Chinese
commies have blocked any true investigation, into the origins of the virus.
There are all sort of possibilities. I am 90% confident that the virus was created in a lab. But even with this theory, there can be two possibilities. Either the virus was accidentally released from the Wuhan Institute of Virology laboratory, or it was deliberately released by some agency which wanted to hurt China. If the latter case is true, then there are not many countries that are capable of doing this.
However, the Chinese were able to create vaccines in a relatively short time period. And these vaccines have proved to be very effective. Now this makes me suspicious once again. China is much behind countries such as USA, Russia and the United Kingdom as far as medical technology is concerned. How they managed to invent highly effective vaccines in such a short time period?
