So the lecture starts with quackery as well. At no point does he say that he is using the scientific method to verify any claims. Instead, he says that the religious people and scholars are right because of magic.
He talks like a duck and walks like a duck. If these religious quacks had made their claims with science, they wouldn't have been ignored. Instead, they made their claims with magic and then retconned their claims to fit the actually believable results from science. It's always the same with these nuts.
