I am always puzzled by the gear-shifting exegesis attempted in Genesis 1:14 by those who refuse to accept that the days of creation are literal, 24-hour days. God said that the sun/moon/stars would be to measure “seasons, days, and years.” Old earth creationists, theistic evolutionists (and atheistic evolutionists) proceed this way: “OK. Seasons are obviously seasons. We’ll admit that this is literal and normal. But wait! *jerky gearshift in the middle of a sentence* Days must be figurative and allegorical. It cannot be literal in meaning. OK *jerky gearshift* now it goes back to normal and years are actual years.” That’s the worst kind of intellectual dishonesty. That’s making the word of God say what you want it to say. It’s called eisegesis. But answer this question honestly: If “days” are not normal 24-hour days, but are unspecified long periods of time, what, pray tell, are seasons and years? And don’t forget that God said the lights were to “separate the day from the night.” If day doesn’t mean the lighted portion of a normal 24-hour day, what then, is “night”?
We measure seasons by movements of the sun and moon (e.g. solstices). We measure years as 365 periods of daytime and nighttime. The position of the sun even tells us we need to add a quarter-day every four years. We speak every day of the common measurement of day and night. The first occurrence of the word ‘day’ (Hebrew yom) appears in Genesis 1:5. “God called the light ‘day’ and the darkness He called ‘night.’ And there was evening and there was morning, one day.” The very first time the word ‘day’ is used, God Himself defines it for us as one cycle of sequential periods of light and dark. God could not have spoken more clearly or plainly. Just because men have attempted to confuse the matter is no reason to refuse to accept God’s straightforward definition. It’s not that difficult, people. Really.
