Uvas,
Thanks. That is an excellent point. Evening and morning sounds like a 24 hour day. However, I could also see it used to demonstrate progression (i.e. from dark to light or from chaos to organization.
To attached a number would mean that each period of time (Hebrew: yowm) would be equal in length like a 24 hour day. Otherwise for example, three "yowm" of different lengths would make no sense to be categorized together in that way. So when we speak of the day ("yowm" of Israel in the Wilderness, that was just one period of 40 years. We would not look for more periods of time.
However, let's assume you are correct that the days in Genesis are 24 hours periods of time. Would you then feel that looking to science for evidence of creation would be a waste of effort? Do you have a thought on how long it took to create the universe? Again, should Christians look to the evidence of science? If not, then why not? After all, don't we look to archaeology to confirm Bible stories and history?
You are welcome to answer, but don't feel compelled. These are just questions that come to my mind.
