Hi Justin,
The Bible says nothing about the ‘Big Bang’ simply because the people who wrote it did not aim to explain the Big Bang theory or discuss science. But does this mean that the Bible is wrong to talk about creation the way it does? The answer is no. The people who wrote Genesis 1 and 2 wrote about how the universe came to be in terms that they knew and understood at the time. In fact, they were not writing to answer the question of how the universe came to be but why the universe is the way it is. From Genesis 1 to 3 in the Bible, we learn a great deal about who God is, who humanity is in relation to God and the rest of the universe, and why there is such a mixture of good and bad in the world. Genesis 1 shows us that whatever way the cosmos came into being, God was the one who was the active agent doing the work. It shows he is a powerful God able to bring the cosmos into being with just a word. It also shows that humanity shares a special place in the cosmos as the only creature who has “the image of God” and because of that, we are special in God’s eyes. Genesis 2 shows us that we have been given responsibility over the earth, to rule it and use it but only under God’s authority. Genesis 3, however, shows how humanity rebelled against God and the consequences of that. What Genesis does not set out to do is to explain scientifically how the universe came into being. If the Big Bang theory is indeed right, then I would be quite happy to speak of God actively creating the universe through the process of the Big Bang. They are not contradictory. I hope this helps you in your understanding. For more information, have a look at:
