* There is a question that I ask myself very often, it is a question that doesnt have an answer. How was the world created? There are different theories on that theme, but here are 2 man theories in which we believe in, the Big Bang theory (scientific theory) and the Creation theory (religious theory). We cannot say that one theory is right and one is wrong because they both have evidence to back them up. How was the world created, is just one of many questions that will probably be a mistery for a very long time. Word count: 97 * 13.75 billion years ago, something happened in our universe that not even world known scientists can fully explain. We know so much complex information about our universe, but why can't we know how it all started. The Big Bang occurred approximately 13.75 billion years ago, which is the considered the age of the Universe. We think that it occured 13.75 billion years agon becaus, thats how old the oldest stars are, and we think that stars began to form almost immediately after the Big Bang. Space and time, according to scientists like Steven Hawking, George Ellis and Roger Penrose, were created after the big bang. The three scientists performed math calculations to prove their ideas in the 1960's and 1970's. ''When the Big Bang happened, it let loose a huge amount of energy into a small Universe. The Universe immediately started to get bigger and bigger and making more space (and it is still getting bigger today).'' That is one of many facts that the Big Bang actually occured. The earth was created 5 billion years ago. Before that, it was just a hot, molten, spinning ball. There was no life on it. Because it was so hot, there was no water on it and the athmosphere wasnt created yet. After time, it started to cool down and when it reached under 100°C, that is when the 1st life formed. During the
