It had to come from bats Bambino. It's 92% similar genetically to several bat coronaviruses. I believe I read 98% for one. The question is whether a bat virus was modified in a laboratory to make its spike proteins able to more readily bind to human ACE2. The furin cleavage site theoretically could be created by combining a couple of coronaviruses. But regardless you'd have to start with a bat virus. More here:

Those insisting on a natural origin say the virus lacks genetic features that would show it to have been deliberately engineered. But it’s also possible that SARS-CoV-2 evolved naturally in the wild before it was brought into a lab to be studied, only to subsequently escape. The Wuhan Institute of Virology, which many see as the likeliest site of a breakout, houses one of the largest collections of coronaviruses in the world.
The problem is the Trump worshipers on here, like there hero don't believe in science.
