For the record, I have no problem with accepting the days in Genesis 1 as seven 24 hours days.
I believe it's illogical to hold to 24 hours day for creation. But that's just me, and I wasn't convince when I visit the Creation Museum or any Scriptural proof-text. To me, the word "day" in Hebrew language has many meanings. It can be a 24-hour day and also be a long period of time day. That is what divides Old earthers from Young earthers. From the Genesis account 1, there are descriptions "evening" and "morning" for the separate six creation days. Of course, when you think normally about 24 hours (like the average Joe does), then it would be "from evening to evening" (24 hours) or "from morning to morning" (24 hours). I am not suggesting two days equals one day or 12 hours equals one day. But this literary device simply doesn't follow our modern thinking and conception of day pattern. So, something more is going on besides a 24-hour day.
And there was evening, and there was morning—the first day. (vs. 5).
And there was evening, and there was morning—the second day. (vs. 8).
And there was evening, and there was morning—the third day. (vs. 13).
And there was evening, and there was morning—the fourth day. (vs. 19).
And there was evening, and there was morning—the fifth day. (vs. 23).
And there was evening, and there was morning—the sixth day. (vs. 31).
But then, there is no such description of "evening" and "morning" as a boundary being assigned for the seventh day. Why? There may be some Biblical clues for an answer. The description denotes the idea that each separate sequence days there was a starting point (evening) and a ending point (morning). This many imply that the seventh day is continuous and on-going. God's rest is finished, but we are still in the seventh day.
Genesis 2:1-3 Thus the heavens and the earth were completed in all their vast array. By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work. Then God blessed the seventh day and made it holy, because on it he rested from all the work of creating that he had done.
The Creator 'Jesus Christ' said:
John 5:16-18 So, because Jesus was doing these things on the Sabbath, the Jewish leaders began to persecute him. In his defense Jesus said to them, “My Father is always at his work to this very day, and I too am working.” For this reason they tried all the more to kill him; not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God.
This is about the Sabbath day and alluding to the idea of God resting in (Genesis 2:3). Jesus Christ is not a deist. God's rest has another significant, then a visual concept of a non-omnipotent God sitting on a throne asleep for 24 hours (Hebrews 4:9). The Father has been working from the very start of the seventh day up to this very day of age. Or in other words, working up to his very time era, and even, in our time era too I may add. This strongly suggests God finished resting, but the seventh day of resting had not yet ended since we are still in the seventh day. Even the author of Hebrews appeals to Genesis account.
Hebrews 4:3-8 Now we who have believed enter that rest, just as God has said, “So I declared on oath in my anger, ‘They shall never enter my rest.’" And yet his works have been finished since the creation of the world. For somewhere he has spoken about the seventh day in these words: “On the seventh day God rested from all his works." And again in the passage above he says, “They shall never enter my rest.” Therefore since it still remains for some to enter that rest, and since those who formerly had the good news proclaimed to them did not go in because of their disobedience,
This implies that seventh day is still continuous and on-going. God has foreordained certain people to enter rest or others not to enter rest. Of course, you didn't physically exist in the start of the seventh day. You haven't been created in your mother's womb yet. But the fabric of this is still unfolding from the very start of God's rest to this very day of age. From creating Adam and Eve up to you and I, through the course of time. The Bible doesn't teach another "day" to follow the sequence of the 7th. day, but the seventh day is today. Not yesterday or tomorrow, but today. Unless the eight day is still yet to come after the resting is finished.
God again set a certain day, calling it “Today.” This he did when a long time later he spoke through David, as in the passage already quoted: “Today, if you hear his voice, do not harden your hearts." For if Joshua had given them rest, God would not have spoken later about another day.
Therefore, it seems unreasonable to conclude that the references to “evening” and “morning” in Genesis 1 can refer to normal solar days. Young earthers suggest there is no sun or moon in the sky until the fourth creation day (Genesis 1:14-15). The obvious. The textual considerations seem to lead one to conclude that these are not normal days as people understand days. These creation days are long period of time, which are meant to be understood as analogous to human (24-hour) workdays. Not to be taken in a literal sense. Since the seventh “day” continues, as Scripture indicates, it could imply that the other six creation days were also long periods of time, rather than just 24-hour days.
