Moon Dance

It seems that, a very long time ago, Earth may have had more moons that just the modern one. Having rocks the size of small buildings smash into the planet as the result of their orbits decaying doesn't sound like too much fun. I wonder if they'll be able to correlate a mass extinction or two with such events?
