Seems pretty straightforward to me. The Chinese said it came from a market, but never found a single animal in that market with COVID.

Apparently "No reports are known to be available for SARS-CoV-2 test results from these mammals at the Huanan market" and "we do not have access to any live animal samples from relevant species" and "The animals on these farms (nearly 1 million) were rapidly released, sold, or killed in early 2020 … apparently without testing for SARS-CoV-2 … Live animals sold at the market … were apparently not sampled either."
What would you accept as evidence of "no lab involvement"?
Not finding such evidence has WithinReason saying "There is also no evidence that the epidemic had no lab involvement."
one cannot prove that ghosts do not exist

The scary part is that there's every reason to expect this to happen again and again.
