' do an enormous amount of damage to the evolutionary theories'

No it doesn't. First, these things do change. They're not exactly the same species. Second, there's nothing in evolution that says that species have to die off. Third, there are many species that didn't die off after the asteriod hit. And finally it's still not entirely certain that the asteroid alone is what killed the dinosaurs.

Finally, this is a science board, not a religious board. The preconceptions mandated by your cult are irrelevant.
