In geologic terms it is.
3 million years is NOT a sudden extinction. A meteor should have wiped out whatever it was going to wipe out in a century or two. The Darwinists would have it that Man as Human isn’t 3 million years old. It might be “sudden” in a geologic sense but it is not sudden enough to admit of a meteor explanation for the extinction of a whole class of animal life. That explanation is going to have to be narrowed down in time a LOT.
