According to scientific accounts, about 15 billion years ago, at the behest of the Creator, a big cosmic ball came into existence in space. This contained all the particles from which the various parts of our universe have been formed. Again, at the command of God, there was an explosion in this great cosmic ball which scientists refer to as the ‘Big Bang’. After this explosion, all its particles were scattered throughout the vastness of space. Later, according to the Creator’s plan, they began to assemble themselves in different forms.
