Earths valcanoes
Weathering, plate movements, and volcanoes destroyed many of the craters. The factors contribute to the lack of evidence of heavy bombardment of earth.
This evidence was subducted or, if not subducted, weathered; since Earth was and still is a "living" planet, meaning a planet with active plate tectonics and an active hydro/atmosphere. This activity is in contrast to the Moon, where plate tectonics stopped shortly after its formation and where a hydro/atmosphere could never form. Both because the Moon was simply too small (and thus too light) to sustain plate tectonics and to keep volatiles with him/her.

On the moon and the other planets in our solar system, the lack of an atmosphere and oceans means that there is very little going on there to change the surface features. Because of this, most of the craters resulting from asteroid hits that happened even millions of years ago are still visible today. However, on earth, weather and geological activity (volcanoes and tectonic plate movement) both reshape the surface of our planet in a relatively short timespan. Anything that hits the ocean will, or course, not leave a crater, and over time craters on land become smoothed over by wind and rain. Some evidence of asteroids striking the earth is still visible today, such as the famous Arizona crater. The asteroid strike that caused this crater is thought to have struck about 50,000 years ago, a relatively short time ago in geological terms.
Evidence of common descent of living organisms has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating that all life on Earth comes from a single ancestor.
Cambrian perod
The Archean Eon is the period in which the first life on Earth appeared.
Scientific evidence suggests that life began on Earth approximately 3.5 billion years ago. The Earth formed 4.5 billion Years ago. The Earth was a dead planet for about 1 billion years. Some evidence would suggest that the first forms of life began more like 3.8 billion years ago, in which case the Earth was dead only 700 million years. The study of the processes which resulted in the beginning of life is called Abiogenesis. If it worked the same on other planets on other Sun in other galaxies, life may have begin 10 billion years ago in other galaxies. See related links. Note also that there are dozens of explanations for the beginning on life on Earth, including many based on religion.
Wormicompost is a process of creating compost or commonly known as fertilizers with the help of earth worms. Usually solid waste from canteens and plants are decomposed by earth worms and after a certain period of time, it is converted into a useful form of fertilizer. The waste is dumped in a dig hole and covered with soil and hundreds and thousands of earth worms in it.

Weather Most of the evidence has been eroded away by the action of wind and water.
