I confront Mathis with this point, and he counters that evolutionary theory is also untestable. This is patently untrue—to give just one example, scientists have witnessed speciation, the arisal of a new species from an old one.
When I point this out, he interrupts me immediately: “Whoa! Wait a minute! Please send me whatever material you have that demonstrates that we can observe speciation because I have not seen anything. I’ve never heard anyone even claim that!”
Is he serious? He’s just produced a film about evolution, and he’s never heard of the fact that speciation has been observed and thoroughly documented in the scientific literature? I’m stunned. I send him peer-reviewed research confirming this fact via e-mail, and he later responds, “This isn’t an important argument for me.”
