How did the coronavirus (COVID-19) start?

A Chinese virologist, Dr. Li-Meng Yan, has claimed that COVID-19 was human-made in a lab in China and released a report backing the claim.

Dr Yan posted a paper on the the open-access repository website, Zenote. The paper examines evidence showing that SARS-CoV-2 is likely a laboratory product created using bat coronaviruses ZC45 and/or ZXC21 as a template and/or backbone.
