Question

How many theories are there who explain the origin of the earth

Answer 1

Pebble accretion theory:

This theory states that the planets were made from small pebble-like particles which came together to form bigger units. This theory explains the formation of the four planets: Mercury, Venus, Earth and Mars.

Note: The solar system is considered to form 4.54 billion years ago. There are many theories that explain the formation of Earth and other planets. Some even say that all the planets are a part of the sun and are formed when some fragments of the sun fall off from it.
