Your comments sound like the virus was humanly manipulated which can also be called weaponized

In 2017 when the article was finally published, took 2 years to put together all of the test results in a paper after the testing stopped in 2015. The Chinese government was concerned with SARS-CoV outbreaks that have a 30% mortality rate. And they were very proud of their science sector and accomplishments. Allowing the recombination formula to be shown to the world was them showing how advanced China was in that science and SARS-CoV research. Recombining the more lethal 11 strains they found in the bat cave into chimeric versions allowed them a level of safety to more easily observe the ACE2 path the virus used to infect cells. AIDS\HIV uses the same vector and in 2005 Hydroxychloroquine\Chloroquine was tested and found to have salutary effects against HIV1. And in laboratory settings it was found to inhibit the ACE2 vector SARS-CoV used to infect human cells.
Honestly, I suspect a researcher screwed up and had a Lab boo boo and carried one of the less lethal chimera versions home with him. The parent 11 SARS-CoV found in the bat cave are not novel. COVID-19 is considered novel because it has never been seen before. But, by looking at it's DNA finger print it was traced to the horse shoe bats carrying the original 11 SARS-CoV variations in China. And how would anyone know about those horse shoe bats? The 2017 peer reviewed paper I linked becasue it's all there in scientific blue print form. If the CCP wanted to spread a virus they would have created a chimeric MERS virus and let the blame fall on the middle east since they have many military and diplomatic missions in that region. MERS has the same 30% mortality rate and is in the SARS family. But, it would have been easier to shut off the middle east than the Chinese who have direct flights now into the EU, Middle East, Asia and the USA. And with those direct flights, Chinese would carry it home to China and everywhere else leaving the Middle East to hold the bag so to say.
They had a Lab boo boo and won't admit it to save face.
