OK, I would like to take some time to discuss a little more about the conspiracy theory on the potential leak of the SARS-CoV-2 virus from a Wuhan virology lab. I find this theory to be even more unlikely than the bioweapon hypothesis.
Let me first say that, a virus has to go through two major hurtles to successfully transmit among individuals of another species. It has to acquire multiple mutations to successfully jump from species A and species B. Then it has to acquire multiple additional mutations to transmit among individuals of species B. Take the SARS-CoV-2 virus, it starts out in bats. It must acquire numerous mutations to jump from bat to human. Then it stays in a "bat-to-human" mode for a long time until it acquires additional multiple mutations in order to do "human-to-human" transmission. Both processes take a long time to finish, decades and maybe centuries.
A good example is the MERS virus. For many many years, the virus stayed on camel and did not affect any human including the camel caretakers. Then, some viruses managed to jump to human, accomplishing the "camel-to-human" jump. However, these virus still could not do "human-to-human". Thus, for many years, we see camel caretakers get sick after contacting their camels, but did not get their families and friends sick. Finally, some virus acquired additional mutations and finally able to do "human-to-human" transmission. These processes took a long time to finish.
Then, let's look at the lab leak scenario. Let's keep in mind that, in this scenario, it was a natural virus being leaked into the public accidentally. As President Trump said, someone made a stupid mistake and did a stupid thing. So natural virus and accidental leak. Under these assumptions, the SARS-CoV-2 virus would have to undergo ALL the necessary mutations naturally without human help (keep in mind that this is not a genetic manipulation scenario, which has been totally and entirely and completely disproved and refuted by the scientific community, intelligence community, President Trump and Secretary Pompeo). As such, a natural Coronavirus is first isolated from bats in the wild. Since most of the bats in the wild do not contact human, most likely these viruses had not contacted any human. Then this virus is kept in a lab, living comfortably in flasks and jars designed to give them the most ideal environment and nutrition. They still do not contact human since even the sloppiest techs in the sloppiest labs would not intentionally expose themselves to terrible viruses on a regular basis. So no human contact and very little chance for the viruses to acquire mutations to adapt lives in human bodies.
Then one fateful day in late 2019, someone accidentally gets some of these viruses on them. So this would be the first time for these viruses to see a human being. Then this person walks to the wet market some minutes to hours later. This would again be the first time for these viruses to see a whole bunch of human beings. So, in a few minutes to hours, these viruses would have to undergo dozens and dozens of mutations, which normally require decades to centuries to acquire, to complete "bat-to-human" jump and "human-to-human" jump. Again, either of these steps would normally take decades to centuries to finish by countless different populations of viruses and different bunches of human beings. I don't think this is possible even if these viruses have been blasted by tons of intense radiation to speed up mutation frequency.
So, within a matter of a few minutes to hours after being in contact with human for the first time, a natural bat virus suddenly acquires dozens and dozens of mutations to finish "bat-to-human" and "human-to-human" jumps??? This is physically impossible in the natural world. Of course, virtually everyone in the world has ruled out the possibility of any genetic manipulation. Then lab leak is also impossible.
The proponents of the lab leak scenario have listed so many examples of previous accidental lab leaks all around the world. However, all these examples involve the kinds of pathogens that have already been capable of infecting human before they are put in labs. Like Ebola and malaria, they have been isolated from patients and have possessed the ability to infect human. Of course, immediately upon being leaked out, these pathogens have no problem re-adapting their favorite living condition in human bodies. The SARS-CoV-2 virus is obviously very different. It's a bat virus and has not seen any human before the hypothetical leak.
Of course, the virus can be leaked decades ago, allowing enough time for the virus to mutate naturally and jump back and forth between bats and human and finally accomplishing human to human transmission (much like the MERS)... but what is the evidence of that? Plus, the P4 lab in Wuhan was built only a few years ago...
