If someone separate them by media says, twitter says, science says, conspiracy says? It will be great.
For the current virus[2], the time and place of transfer is unknown, but the current thinking seems to be that it followed the same chain as SARS (bats -> some animal -> humans).
There is absolutely zero evidence from credible scientists of any kind of "escaped from the lab" or "bioweapon" source. These are just conspiracy theories.

Just because some people don't believe that is likely, that does not mean it is not _plausable_
Is it plausible that there could be a biological lab in Wuhan? Yes, in fact, there is one.
Is it plausible that some countries do research on biological weapon? Yes, in fact there are multiple cases of such occasions: https://en.wikipedia.org/wiki/United_States_Army_Biological_...
Is it plausible that biological lab can leak bioweapon? Yes, in fact this happened before, e.g. https://en.wikipedia.org/wiki/Sverdlovsk_anthrax_leak
There is --zero-- evidence of a bioweapon.
So it's better in the sense that it's reflective of reality, which also happens to not inflame international relations at a crucial time.
