Birth of earth

It is totally a bizarre question, that how does our earth evolve. In order to answer this we have to go back for about 4.5 billion years from now. When our proto sun which was a star among others , started collapsing under the force of heavy gravity. Its temperature shooted up to millions of centigrade and absorbing power from its neighboring stars, finally forming a huge star with temperature and pressure just closing to a level for nuclear fusion reaction to take place. After a supernova explosion, many amount of debris fell out of this region. At this juncture, the nuclear fusion reaction is stopped at the outer edge of the sun while the sun gets contracted to one point. The debris from sun, that is moons, planets , asteroids, comets and so on. Very large asteroids are attracted towards the sun’s core region where the center of gravity is high. At some particular point of time ,there might be chances of getting collision by two or more large asteroids ,which gives to birth of a plant in our solar system. When two large asteroids collide, there is a huge breakdown that is certain amount of gravitational power exists in each asteroids which gives rise to continuous and constant rotation between them. Later these two clubs down and in continuous rotation give rise to sphere shaped planet. Some of the debris situated at outer ring of solar system, it will fall back and some may even fell on the planets during their journey. These frozen debris resulted as ocean in our planet earth.
