Fortunately for him, Buddhism is cleverly designed to contain no scientifically falsifiable claims.

A Buddhist friend told me that at a class in a temple, the teacher mentioned four types of creation, of which one was spontaneous generation- like maggots spontaneously generating in meat. My friend interrupted to say that, no, that's not actually what happens, and that people did experiments to prove that it didn't happen. (My friend was too polite to mention that the experiments were 350 years old.) If I remember correctly, the teacher said something like "huh, okay," and went on with the lesson, leaving out any parts relevant to spontaneous generation.
