Yes, Jeff himself provided that quote, on the thread I cited above, here – where he cited Clarey’s book as his “second” major purported piece of evidence supporting YEC.
@jeffb should not be unaware that Clarey’s credibility is in doubt, as @AllenWitmerMiller contributed this video to that thread:
This means that Jeff is ‘flogging a dead horse’ at all levels, both by repeating his claims of (non-existent) new evidence, in recent decades, for YEC, and in citing Clarey’s discredited claims as part of that ‘evidence’.
It would seem that ‘Morton’s Demon’ is particularly strong in Jeff – allowing in the claims of the likes of Clarey through, but carefully filtering out the reception of these claims by scientifically-literate audiences, leading him to try to use them over and over again – with disastrous results.
It should be noted that this wasn’t even the first time that Clarey’s book came up on this forum: it got its own thread back in 2020 here:
