Is there somehow more evidence of natural origin than lab leak? By common sense, this is what I mean: the strain of coronavirus that caused covid-19 was very strong, much stronger than any previous strain, and we have seen many. Common sense says we have seen all the strains Nature could throw at us already, and none have been that deadly. So common sense leads to looking for evidence i new light, in new places.

Also, evidence is not fact. Evidence is anything. Evidence was O.J. Simpson's hand didn't fit the glove. That was weak evidence, but that turned into "proof", via not-guilty verdict. Even proof is not fact (there are no facts lol). Evidence is anything you can find to solve the crime. After you collect evidence, you go through it at piece together the story. Read a book yo.
