Why I believe the “days” of Genesis 1:1-2:4 are normal days of about 24 hours each.
The primary reason is that I sincerely believe that is what the Bible teaches.
The first time the word “day” is used in Genesis 1:5 it means the daylight part of the day/night cycle.
In Genesis 2:4 the word day means a longer period of time.
In Genesis 1:5b; 1:8; 1:13; 1:19; 1:23; 1:31 the word day means a normal day of about 24 hours.
The reasons I believe this is true are:
* Genesis is written as simple historical narrative
* Exodus 20:8-11 clearly teaches that the creation days were normal days
* God said He created the world in six days Exodus 31:17 (see 31:12-18)
* The author’s original audience would have understood the text to mean normal days.
* In the Old Testament the word day combined with a number and/or the phrase “evening and morning” (as it is in Genesis One & Two) nearly always means a normal day.
Scripture, not science, is the ultimate test of truth (start with the Bible and compared everything else to it; not vice versa).
God can do whatever He wants to do. The only question is: “What does God say He did?” It seems plain to me that He said He created in world in six normal days.
