Eyewitness testimony in the courtroom is evidence to be considered by a judge or jury and is now known to be highly unreliable and subject to all sorts of biases. So, in the world of science personal testimony is useless.<quoted text>
Testimony is evidence. But just deny the testimony of others. That would be so much more convenient for your dogma.
Only in religion do people believe absurd extraordinary claims that have no evidence to back them up. Confirmation bias much?
