RJH:The days of the creation were not literal 24 hour days. The earth was not as it is now. And besides, why would recogning of a 24 hour day be needed as no man was around and no time pieces (clocks or watches) existed. The days of creation were "epochs of time" (time periods) each day spanning many 1000s of years. The expression "day" should be understood in the context of "my grandfathers day" or "in the day of the horse and buggy." Not a literal 24 hour day.
I said earlier:
"The Hebrew word "yom" is translated as day in Genesis. Just as our word "day" can have different meanings based on its context, so can the word "yom". For example, in the Old Testament "yom" is translated to mean a 24 hour day 1109 times. It means a long, long period of time--such as an age--about nine times.
However, every time the word "yom" is used with the term evening or morning in the Bible, it means a regular 24 hour day.
Every time the word "yom" is used with a number, such as "40 yom" (40 days), it means a regular 24 hour day.
What we now see is that in Genesis chapter one God is going out of His way to emphasize that each day is a normal 24 hour day. For example in verse five He says:
"And there was evening and there was morning, one day."
Verse 8: "And there was evening and there was morning, a second day."
Verse 13: "There was evening and there was morning, a third day."
For each day of creation the pattern is the same: evening, morning, number, day. Just part of that pattern, for example using the words "evening" and "day" together, tell us it was a 24 hour day. But God tells us in three ways -- evening, morning, number -- that the word day means... an ordinary 24 hour day.
God is making it very clear: He created everything in six ordinary days."
RJH you have not given any sound reasoning to justify your claim that the creative days definitely would not have been 24hr days. Maybe you would have a better argument if the verses read: "there came to be many evenings and many mornings, a second "yom." However it doesn't.
Also note:
Genesis: (Third day)
"And God said, 'Let the earth put forth grass, herbs yielding seed and fruit trees bearing fruit.'"
Science:
This section of Genesis' third day is out of sequence. Plants, grass, and fruit bearing trees, did not appear until AFTER sea creatures! Although microscopic single cell algae (bacteria or archaea microbes) are a plant and appeared at this time, it is not the advanced forms of plant life described in Genesis. Again, the appearance of flora did not take place at this time according to contemporary science.
