The virus originated from chinese horseshoe bats. It can't just randomly teleport to some other country on the other side of the world to start an outbreak, before existing in human population of China.
Well no, but also in the US there are research facilities working with Coronaviruses [1]. I am not advocating for this theory because there is zero credible evidence for it but there are scenarios that would make this theoretically possible.
This is far from certain. The virus has not been identified in the wild. There are several genetically similar viruses in pangolins and bats sampled from China, but Covid combines sequences from at least 2 of them.
Did you realize that there are also bats in Austin, Texas? They live under the bridge there.
Unless these bats are perfectly clean and disease free, after millions of years of evolution. And somehow, only the bats in China, can carry a novel coronavirus?
I’m just pointing out that bats exist worldwide. And they can infect other farm animals. This is not a unique situation to only China.
