It's impossible to prove that it was not grown in a lab, which is why the burden is to show that it _was_ grown in a lab. Until we have that, we shouldn't be sharing stories about how it _might_ have been grown in a lab.
Logically and epistemically sound thinking is what the world needs more of, not less.
I presume you're not a big fan of conspiracy theories - well, a big part of where they come from is the media doing something similar to what you're complaining about, stating what might be true, as unequivocally true. It would also be interesting to know how much of the polarization in society can be attributed to the fantasy world the media projects into people's minds using these techniques.
The probabilistic model of knowledge as just a collection of hypotheses that have failed to have been falsified over sufficient testing is the dominant epistemological view today in empirical sciences. Knowing = Probably Is. It's just a matter of degree, so making the statement "it is not true that we know that, but it probably is the case" is ill-formed in the absence of consistent belief thresholds.
Normally I wouldn't say anything, but you did pull a "well, actually" there, so out-pedantifying seems warranted if only for the humour of the situation.
If you are going to be pedantic, there is no such thing as 'proof' at all. You can only ever demonstrate that you are 9X% likely to be correct.
Maybe the murder caught on camera is a lost identical twin, or victim of a very elaborate frame-up. The standard for conviction is beyong reasonable doubt. What is reasonable?
Maybe we have laws of physics wrong, and next tuesday sun will rise in the west, and Jesus rises from the dead. Again.
Do yoy trust governments and scientists? They used to claik smoking is a great way to get your essential vitamins.
Do you trust your own mind, because research has shown people can be manipulated into remembering things that never happened.
Ib radical doubt, the only thing you can proove is 'I think, therefore I am".
Also I'd like to contest that the nature study is "suggestive" that its not man made. Finding Elvis dead in Vegas is not "suggestive" that Elvis is dead.
If you are asking me to proof a negative, that's virtually impossible.
