Your entire post makes a bit much of the word 'explosion.' The word only applies in the context of geologic time. In this event a variety of new species appear in the fossil record in the relatively short time span, geologicaly speaking, of around 40 million years. That's still 40 times the amount of time the human species has been on this earth--and unspeakably vast, please note, compared to the amount of time Young Earth Creationism allows for
anything. The event is not an instantaneous, miraculous
Ta-da! It just happens to be an extremely fertile moment--all multiple million years of it--in earth history.
