"The Hebrew day began at sunset. Each day consisted of a dark portion and a lighted portion. This same sequence is given for the days of creation. Therefore these days could not have been symbolic of long time periods.
In the latter part of the eighteenth century the French philosopher Buffon propounded the theory of "epochs of the earth," assuming that past time had been divided into six or more geological epochs of unequal length. Theologians seized upon this idea as a means of harmonizing Genesis with the growing science of geology.
They adopted the viewpoint that made the days of Genesis merely symbolic of geological epochs. This new theological interpretation became the "day-age" theory of the middle nineteenth century."

And God called the light Day, and the darkness he called Night.
And the evening and the morning were the first day.
