It’s human nature to ask questions and try to find the answers. There are many questions which are always asked, and people have tried to answer them throughout our history. And there are many questions to which we do not yet have answers, at least satisfactory ones.
One of these questions is about the origin of the universe. Everyone wonders how this all began. How did the universe begin? Or has it existed forever? What was there before it all began?
Current scientific understanding points us toward the fact that our universe has not existed forever; it had a beginning. It started with a big explosion popularly known as the ?Big Bang? about 13.8 billion years ago.
