On the fourth day of creation, God created the sun, moon and stars to give light to the earth. If God created them on the fourth day, is this proof that the first three days were longer than 24 hour days?
14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: 15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. 16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. 17 And God set them in the firmament of the heaven to give light upon the earth,18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.19 And the evening and the morning were the fourth day
Day-age creationists have the theory that this is an indicator of an old earth age. The presumption is that the absences of these celestial bodies imply the impossibility of a 24 hour day. So, day one through three was probably much longer than a 24 hour celestial cycle, which could be the answer to the evolutionist assertion that the earth is old. This theory leads us down a path that causes us to contradict scripture and undermines a vital principle of God’s word.
