If he was wrong this claim would be so trivial to refute that sources seem entirely pointless.
lawnchair_larry made a claim about "nobody credible" believing something. As a lay person in the field, I don't know who these credible people are. Therefore I asked whether lawnchair_larry could tell us who one or more of these credible people are, and where we can read more about what they believe to be true about the situation.
As the other commenter stated, if someone thought that someone credible made that claim they could simply provide that source, which both (1) involves asymptotically less effort for everyone involved and (2) under reasonable assumptions is at least as effective.
“Sir, I’m going to need for you to list for me all the crimes you didn’t commit last Saturday.”
This is most definitely a rather silly request.
Can you prove that magic doesn’t exist?
