The Bible does not contain much specific information about cosmology. For instance, the Bible doesn’t directly tell us the earth’s shape, nor does it tell us whether the earth moves around the sun. However, we can glean some information from days two and four of the Genesis 1 creation account to develop some basic understanding of biblical cosmology. This leads to some conclusions that are contrary to what most modern cosmologists think. Surprisingly, these conclusions provide an explanation for the cosmic microwave background (CMB) that is considered to be the best evidence for the big bang model.
