翻译下这段吧

This work could be significant in other ways. While the rate of asteroid collisions experienced by early Earth generally declined over time it may have spiked some 3.9bn years ago during a postulated event known as the Late Heavy Bombardment (LHB). What are taken by some as signs of the LHB pockmark the static surfaces of Mars and the Moon. Earth’s constant ructions however will have destroyed any signs of it. If Dr Johnson is right then the formation of the continents could be the first earthly evidence of one of the solar system’s most dramatic moments.

这项工作可能在其他方面具有重要意义。虽然早期地球所经历的小行星撞击率通常会随着时间的推移而减少，但它可能在大约39亿年前频繁遭受各种小天体的撞击，这就是著名的“后期重度轰击”（Late Heavy Bombardment，简称LHB）事件。一些人认为后期重度轰击的迹象在火星和月球的静态表面上留下了痕迹。然而，地球的不断抗击将破坏它的任何迹象。如果约翰逊博士的结论是正确的，那么这些大陆的形成可能是太阳系最具戏剧性时刻的首个地球证据。
