Young-earth creationists insist their model makes real, testable scientific predictions. So I decided to actually go looking for the best examples and hold them to a strict standard: was the prediction stated before the evidence came in, and does it actually distinguish a young earth from an old one?
In this video I define three categories of "prediction," from genuinely risky forecasts to after-the-fact accommodation, and then work through the six strongest examples young-earth creationists point to, including Russell Humphreys' planetary magnetic field prediction, rapid geomagnetic reversals, dinosaur soft tissue, detectable carbon-14, Nathaniel Jeanson's molecular clock claims, and hybridization within created kinds. Only one case comes close to holding up, and even that one turns out to be far less decisive than creationist presentations usually suggest.

49:00 The real distinction: prediction versus accommodation
53:30 What a genuine young-earth prediction would look like
