What are the 5 theories of Origin of Earth

 Theories of Origin of Earth;   Before going to the theories let us understand what theory is ? A repeatedly tested or widely accepted statement is called theory. This statement is also used to make futher predictions about a natural phenomenon. There are different theories about how earth was formed and no one theory can tell exactly how earth came into being. Scientists believe that the earth was formed more than 4 billion years ago. They found this by studying the radioactive elements contained in the rocks.     1) Creation theory or Mythical Theory : Muslims believe that our Earth and the whole universe is made by Almighty Allah .Christians also believe that the earth was made by God on Seventh day . The Chinese believe that the earth was created by pan ku, a supernatural being. An important man Anaximander suggested that the earth began from a ball of fire that covered a cold mass. When the ball of fire burst into pieces,these pieces became the bodies in space while the cold mass became the world. A widely accepted statement which have been verified experimentally is called a theory.   2) Scientific Theory :  Scientists  have better explanations ,how earth came into being.These theories are based on long time studies observations and researches made by expert scientists .Scientific theories have been developed by careful study of nutural phenomenon and experimentations.  3) Tidal Theory : this theory was given by Sir James jeans: an English mathematician and physicist.According to him the earth was formed from materials pulled on from the sun. The theory explains that the sun existed alone first ,there came a wandering star near the sun.The movement of the star created a tied that rose very high and it torn away some of the matter and gases from the sun's outer layer. These matter and gases got together and formed bodies that became planets . Our Earth is one of those planets. 4) Nebular Theory:  This theory tells that how the sun and the planets were formed at the same time from a huge cloud of dust and gas floating in space. This material collapsed because of gravity and became a mass. With the passage of time the smaller mass begin to rotate and a disc was formed. There rotation caused a budge in the disc and this budge became. Hotter and hotter and energy was produced and shining (glow) started.This shining mass became the sun and other smaller became planets. 5) Solar Disruption theory and Dynamic Encounter Theory: This theory was proposed by L.Buffon explains that 4or 4.5 billion years ago a star (comet) collided with the sun,Causing some parts of the sun to burst. There parts became planets in the space.
