This guy is a joke!
We know that SARS-COV-2 cannot infect bats and not even pangolins and that the genetic distance (>800 amino acides) is about 30 years (straight line) to the nearest natural virus. But under real conditions these 30 years are a once in a universe live-time chance as all selections (must survive and pass) among 4800 possible changes must happen the right way....
Not to mention that recent computer modelling shows that the original spike RBD has much more affinity to human ACE2 than to any other species tested. Pangolins came a distant second. https://www.nature.com/articles/s41598-021-92388-5
