Hi. Although you present a text, you didn't have any questions about it. This prevents me from giving you any answers. However, to try to help you, I'll explain what this text means. I hope this is helpful for you.
The text above is intended to present facts that prove that Yan Li Meng's allegations should not be taken seriously, as she does not have sufficient academic and professional background to address them. Yan Li Meng is a researcher who claimed to have proof that the coronavirus was a virus that was purposely developed in a Chinese laboratory. Although her allegations have strengthened arguments that accused china of having provoked the pandemic, in addition to reinforcing xenophobic ideas, a research on Yan Li Meng shows that her academic background does not have the adequate elements to reach this conclusion. Yan Li Meng has no training in virology and has not even worked in science, which shows that her claims have no scientific basis, are not true and serve only as fake news.
