The Big Bang Theory

Do you know how was earth originated?
There are many theories in this topic. But the most popular theory is THE BIG BANG THEORY, it was written by two scientists named as: Urey and Miller .And this theory goes on like this.

About 5 billions years ago Sun was huge mass with greatest gravitational power in universe. An asteroid came in front of Sun part. They stroke with each other, the pieces of sun scattered in universe. They were in their own orbits. Due to more gravitational force of sun, they started rotating around Sun in their own orbit. When they rotated in there own orbit for many years, they became round in shape. Earth was in the third. Let us talk about Earth now.

It was a third planet from sun that means it was far from Sun, when it was far it started cooling down. Heaviest thing remain in middle of Earth and likewise it went on, in this way the Earth had many layers: Inner core, Outer core, Upper mantle, Lower mantle and Crust. Vapors went up for 500 to 600 years. The process of Vaporization, condensation and precipitation went on. Let us talk how Seas and Oceans water is salty. Any body knows this? If No let me tell.

There were salt in layer of Earth. When precipitation went on it took all the salt in layer and stored in a deep place, which we call it nowadays by Seas and Oceans.

After this long process some cells formed, they went on multiplying likewise living beings were formed. All the things cooled but middle part is not cooled till now may be it is going cooling on.
