For example, the Bible says that time was created by God when He created the universe.19 Stephen Hawking, George Ellis, and Roger Penrose extended the equations for general relativity to include space and time, demonstrating that time began at the formation of the universe.20 Of course, the biggest coup of the Bible was to declare that the universe had a beginning21 through an expanding universe model.22 The New Testament even declares that the visible creation was made from what was not visible and that dimensions of length, width and height were created by God.23 In addition, the Bible refuted steady - state theory (saying that the creation of matter and energy has ended) 24 long before science made that determination.
