Heavy bombardment is a critical event for life on Earth because it delivered water and organic compounds to the planet, which are essential for life to thrive. It also helped create the conditions for the development of a stable atmosphere and oceans. Without heavy bombardment, Earth may not have had the necessary ingredients for life to evolve.
The heavy bombardment period, known as the Late Heavy Bombardment, is estimated to have occurred about 4.1 to 3.8 billion years ago. This period was characterized by intense asteroid and comet impacts on the inner planets of the solar system, including Earth.
The lack of evidence of the period of heavy bombardment on Earth can be attributed to erosion, tectonic plate activity, volcanic activity, and the geological processes that constantly reshape the Earth's surface over time. These processes can bury, distort, or erase the impact craters and other evidence of the period of heavy bombardment. Additionally, the Earth's dynamic nature and the recycling of its crust through plate tectonics have further obscured the remnants of this early bombardment period.
Weathering, plate movements and volcanoes destroyed many of the craters
The lack of evidence of the period of heavy bombardment on Earth is primarily attributed to geological processes like erosion, plate tectonics, and the presence of water that have erased or altered much of the early Earth's surface. Additionally, the constant recycling of Earth's crust through processes like subduction has also contributed to the limited preservation of impact structures from that period.
The heavy bombardment period occurred early in Earth's history, about 4 billion years ago. Since then, geological processes like erosion, volcanism, and plate tectonics have erased much of the evidence of impact craters. Additionally, the Earth's atmosphere and active geology may have also contributed to the reduced visibility of impact scars from that time.

It was nasty hot with a poisonous atmosphere. There was no life at that time.It was a time of heavy asteroid bombardment.

I assume you are referring to the Cambrian Explosion... It was a period on Earth many millions of years ago after heavy bombardment from asteroids. A huge "explosion" of species and life came to form on Earth.

It was used for heavy artillery bombardment.
