What Is The Day Age Theory? Do The Scriptures Teach This?

The Day Age Theory is a View point held by many who are theistic evolutionists (believe in God and evolution).  Theistic evolution is the combination of the belief of evolution and the belief of creationism.  However the scriptures do not support this view.  Those who hold to the Day Age Theory believe that the days in the creation account were long periods of time, thus allowing evolution to take place.  The Bible itself gives evidence that the days in the Genesis creation account were literal 24 hour days.  The Hebrew word “Yom” which is translated as “day” is defined in the text itself.  Genesis 1:5 declares this was a 24 hour period, and in the literal Hebrew it states “evening was, morning was, day one”.    “Yom”, is the day period in regular succession of light and darkness due to the earth rotating on its axis, and has continued ever since the creation account recorded in Genesis.
If the days were long periods of time as claimed by those who hold to the Day Age Theory, how do they explain Genesis 1:14 (KJV) “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:”.  If days are actually long periods of times, what are the years in verse 14?  This literal day (24 hour period) allowed man to define seasons and years just as we do today on a calendar.  If something as simple as defining the word day can not be accomplished, how can one ever hope to interpret or understand the Scriptures at all?  Whenever the Hebrew word “yom” is preceded by a numeral, it always without fail refers to a literal 24 hour period.  Over 100 times in the Old Testament you will find the word “day” (Yom) preceded by a numeral, and each time it is a literal 24 hour period.   In the verses in the Old Testament where the word “day” (Yom) is not preceded by a numeral, it is not a literal 24 hour period.  Two examples of the use of the word “day” (Yom) that are not 24 hour periods of time are seen in Gen 2:4 (stands for the six days of creation) and Genesis 4:3 (translated as “process of time”).  This can also be seen in Gen 26:8 (a long time) and Psalm 95:8-9 (“Day of temptation” which refers to the wilderness wandering).  There were other words in the Hebrew language that Moses could have used through inspiration to describe long periods of time (“Olam” and “Dor” strictly mean long periods of time), if he wanted to teach the Day Age Theory.  Next, if these days were long periods of time, how did the plants survive without sunlight.  The plants were created on day three, but the sun was not created until day four.  Long periods of time without sunlight would have caused the plants to die.  The evidence confirms the creation account was Inspired and accurate.
