The closest natural relative origin of SARS-CoV-2 was in Yunnan ~700 miles away from the market.
The Wuhan lab collected samples from that area and the lab is only ~10 miles away from the market.
Those wet markets are huge vectors for a viral spread, so a virus being spread there doesn't necessarily mean it started there.
Why that market in Hubei and not first at a market closer to Yunnan? It might be more profitable to transport and sell them there, but it's still a long way to travel and avoid spreading during that time just to end up at a market so close to that lab.
A lot of reasoning around whether a lab leak is more likely doesn't require it to be engineered or modified in any way.
