Always talking about micro-evolution?

Perhaps a very minor quible, but I see no reason why there could not have been multiple biogenesis (note the lack of "a" at beginning) events. The earth's a big place - Why only one?

Richard Dawkins himself single-handedly and unknowingly cause ToE evolution to cease to exist (his theory of punctuated equilibrium forces the ToE into a situation in which it can no longer be falsified, in which case it's no longer testable and can't be called a theory anymore. That's why ToE is usually referred to as FACT in many modern textbooks and scientific writings).
