The Big Bang Model describes the 13.8-billion-year history of the universe from an initial state to present day. Why do we think there was a Big Bang? In the beginning the universe was incredibly hot, dense and rapidly expanding. The Big Bang Model describes how the universe evolved; forming the elements, stars and galaxies we see today. The model does not say anything about how the universe came to be. We have no idea about what happened before the Big Bang.
