I love the opening words to my favourite book, "In the beginning,..."
If you don't believe these very first words of Scripture, then how can you believe the whole book? We cannot go back in time to see how it all began, we need to believe this in faith. Even atheists must believe their theory in faith because they never saw the whole thing with their eyes either, Hebrews 11:1. It takes less faith to believe God's Word then it does to believe the theory of man. I guess that is why God tells us we only need faith the size of a mustard seed, Luke 17:6.
"...God created the heavens and the earth."
