The Late Heavy, as I like to call it. Sounds like a Drum and Bass producer. Anyways:

The Late Heavy Bombardment (LHB), or lunar cataclysm, is a hypothesized astronomical event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago,[1] at a time corresponding to the Neohadean and Eoarchean eras on Earth. According to the hypothesis, during this interval, a disproportionately large number of asteroids and comets collided into the terrestrial planets and their natural satellites in the inner Solar System, including Mercury, Venus, Earth (and the Moon) and Mars.[2] These came from both post-accretion and planetary instability-driven populations of impactors.[3] Although it has gained widespread credence,[4] definitive evidence remains elusive.
