A lot of people are trying to explain that the Big Bang Theory does not oppose the creation story of the bible. According to the Big Bang Theory, there was one big egg that was available then and it slowly evolved in order to form life on earth. According to some people, the evolution of the egg may have been directed by God.
The reason why it started to evolve is that of the instructions that were given by God to the universe. If you think about it this way, it does not seem too unlikely that the Big Bang theory and the story of creation are not related to each other.
