Why a massive meteorite strike could be the best thing to happen to us

Well, they have had an influence on life on Earth. Consider the great Ordovician biodiversity event, which took place around 470m years ago, when there was a big increase in numbers of species. Only recently have geologists found a possible cause: a widespread bombardment of the Earth by meteorites. These would have sterilised an area a few hundred kilometres across – a major ecological disturbance but not a lethal one for a particular species.Sure. Free up space. Sounds fantastic.
In fact, what it would have done is free up space. It would have been like putting a quarry in the middle of an area that has no cliffs. Suddenly, you have all the species that live on cliffs moving into the area and increasing the local biodiversity
I don't know about you, but I'm still not getting excited.
