The day-age theory, espoused by progressive creationists and theistic evolutionists, alleges that each day of the creation account in Genesis 1 represents geologic ages (millions of years) instead of ordinary 24-hour days. Here are six simple reasons to reject this theory in favor of a more straightforward understanding of the text.
1. Whenever the Hebrew word yom (“day”) is preceded by a numeral, it always refers to a solar (24-hour) day (Gen. 1:5, 8, 13, 19, 23, 31; cf. Num. 13:25; 14:33-34; Ex. 20:9-11).
2. The phrase, “So the evening and the morning were the first day” (Gen. 1:5), is used over 100 times in the OT and always refers to a 24-hour day.
3. If “day” in this context refers to geologic ages, then each “day” would be millions of years of continuous darkness followed by millions of years of continuous light.
4. Adam lived through the sixth and seventh days (Gen. 1:26-2:3), but he did not live for geologic ages (Gen. 5:5).
5. The Jews were commanded to work six days and rest one day each week because this was the pattern of creation recorded in the Genesis account (Ex. 20:8-11).
6. If God had wanted to describe creation in six literal 24-hour days, how could he have stated it any clearer?
