Read the links. It's unlikely it started in Wuhan, it's unlikely it came from a lab. 3 early strains have been identified around Wuhan pointing to an intermediary animal host. Humans need to stop taking credit for everything nature does :)
What are the chances, millions of bats interacting with millions of other animals out in nature, or one test gone wrong in a lab that somehow allowed cross infection to an intermediary species that just so happened to facilitate a viable mutation that then jumped onto the researcher or janitor or however it could have exited the lab. Was anyone working at the lab infected?
