What happened when the world started?

Answer 1

According to The Bible, the world was created by the word of God. As you can read in the book of Genesis, chapter 1, In the beginning, God created the heavens and the earth, and the earth was unformed and void and darkness was on the surface of the deep..." And on each of the days of creation, God created more (oceans, vegetation, animals, etc) until finally he created man and woman and then rested on the seventh day.

Not every religion has that exact story, but most religions do believe a god (or gods and goddesses) had the responsibility for creating the world. In some cases, the creation story involved a violent cataclysm, in other stories it involves something the deity thought and then turned into a reality.

But that is not the only explanation for how the world began. In some religions, the belief is that the world always was; it had no beginning. And there is also a non-religious explanation, which does not attribute the beginning of the world to any god or gods. There are several scientific theories about the creation of matter and the emergence of what became the world. One of the most widely accepted scientific explanations about the expansion and evolution of the universe is called the "Big Bang Theory."
