> All other viruses from animals were found very soon after an outbreak.
You assertion is still wrong. It took about 4 years to nail down MERS as coming from camels, and the link from bats to camels to people is still fuzzy. There are several hemorrhagic fever causing viruses believed to come from animals, but with. no known source. We still don't know where Ebola comes from.
People have been looking for the animal reservoir for Ebola for decades, and we haven't found it yet.
A lab leak could be the source for COVID-19, but the lack of an animal source so far isn't evidence of that. It's precisely a lack of evidence.
