Science assumes order and uniformity in the world, and provides ways of understanding what normally happens. The bible teaches us that this order and uniformity is governed and upheld by God. In fact, if there was no God, we could have no confidence that our world is ordered and uniform.
Miracles would of course be impossible for those who do not uphold the laws of science, but not for anyone who did. Science doesn't therefore disprove the miracles recorded in the Bible. Rather, the miracles in the bible prove the existence of God. Indeed, if God wanted to wake us up to his existence you might expect him to do the unusual in order to do so.
Christians differ in their convictions about whether God created the world in six literal days or whether the bible is using the days as a literary device to portray more general truths. What all Christians agree on however, is that science doesn't set out to answer the bigger questions such as “Why are we here?” and “How should we relate to God?” To find the answers to these questions we need to look at what God himself has said in the Bible.(Genesis 1-2, Hebrews 1:3)
