Here's some evidence: if you fart in an elevator, it stinks, but if you fart outdoors, not so much. Viruses, as opposed to farts, don't smell, but otherwise they are similar. If someone coughs outdoors, the aerosols containing the viral particles just spread around and soon their concentration becomes negligible. If someone coughs, or just breathes indoors, the aerosols spread, but if the space is not very large, their concentration will stay elevated, enough to infect other people. With this preamble out of the way, what is the hypothetical scenario where the pandemic starts in the market? Covid does not spread from dead meat, it's an airborne disease. Was there some live bat (or pangolin) that was sneezing in some enclosed space, and some people acquired the virus there? A google search shows links with evidence to the contrary ([1], [2]). Here's and NY Times article [3] that's arguing for the non-lab-leak origin, but you'll notice they are using misdirection (e.g. "dozens of species that can carry pathogens that infect humans" -> ok, this says nothing specific about Covid, but is written to prime the reader to think Covid was among those pathogens). Overall, the simplest explanation is that one lab worker acquired the disease from aerosols in the lab produced by the lab mice infected with the virus. The worker then left the lab and stopped here and there (home too) and left aerosols that some other people inhaled. Whenever it was outdoors, the aerosols did not cause infections, but sometimes when it was indoors, they did. Is it possible that that person went to the market nearby to have lunch or dinner and coughed or sneezed while indoors, and some of the market workers, or co-diners got infected? It does not sound outrageous. You can envision tons of plausible scenarios with an initial lab worker getting infected, but you need to get into contorted scenarios to cook up a theory where some bats from a few thousand kilometers away get transported to Wuhan and fail to infect anyone on their way, then the disease explodes like a bomb in Wohan, and then nobody is able to find evidence of those live bats being sold in that market.
