How Long Were The Creative Days ?

What about the length of the creative days ?
Were they literally 24 hours long ?
Some claim that because Moses-- the writer of Genesis- later referred to the day that followed the six creative days
as a model for the weekly sabbath , each of the creative days must be literally 24 hours long..
{ Exodus 20:11 }

Does the wording of Genesis support this conclusion ?
No, it does not.
The fact is that the Hebrew word translated " day" can mean various lengths of time, not just a 24- hour period.
For example, when summarizing God's creative work, Moses referes to all six creative days as one day.
{ Genesis 2:4 }

In addition , on the first creative day, " God began calling the light Day, but the darkness he called Night."
{ Genesis 1:5 }

Here, only a portion of a 24- hour period is defined by the term " day. "
Certainly, there is no basis in Scripture for arbitrarily stateing that each creative day was 24 hours long.
