It is not. The creation account speaks of the preparation of the earth that had already existed. Now it is being prepared for human to live on. When the Bible speaks of a day it is not referring to a literal 24 hour. To a God of eternity a day can be thousands of years.
2 Peter 3:8 However, do not let this escape your notice, beloved ones, that one day is with Jehovah* as a thousand years and a thousand years as one day. We know the Gensis account cover event that took place more that 4000 years. This can be compared by the age of the people in each generation. On the seventh day it state that God rest. Over 4000 years later it speak on entering God rest. of the verb “has been resting.” That suggests that the seventh day—God’s “day” of rest—was under way in 1513 B.C.E. when Moses wrote the book of Genesis. Is God’s rest day still ongoing? If so, can we enter into it today? The answers to these questions are of vital importance to us. Two lines of evidence lead us to the conclusion that the seventh day was still under way in the first century C.E. First, consider Jesus’ words to opposers who criticized him for healing on the Sabbath, which they construed as a form of work. The Lord said to them: “My Father has kept working until now, and I keep working.” (John 5:16, 17) What was the point? Jesus was being accused of working on the Sabbath. His reply: “My Father has kept working” answered that charge. In effect, Jesus was saying to his critics: ‘My Father and I are engaged in the same type of work. Since my Father has kept working during his millenniums-long Sabbath, it is quite permissible for me to keep working, even on the Sabbath.’ Thus, Jesus implied that as regards the earth, God’s great Sabbath day of rest, the seventh day, had not ended in his day.* God’s purpose was clearly explained to Adam and Eve, but they failed to cooperate with it. Of course, Adam and Eve were only the first humans to pursue a course of disobedience. There have been millions of others since then. Even God’s chosen people, the nation of Israel, fell into a pattern of disobedience. And significantly, Paul warned first-century Christians that even some of them could fall into the same trap as the ancient Israelites. He wrote: “Let us therefore do our utmost to enter into that rest, for fear anyone should fall in the same pattern of disobedience.” (Heb. 4:11) Notice that Paul links disobedience with failure to enter into God’s rest.
This show that each day had to be at least 6000 years each. Because God is still resting and he is going allow another 1000 years for mankind to be restore back to perfection without interference from the Devil. Revelation 20:1-15
20 And I saw an angel coming down out of heaven with the key of the abyss+ and a great chain in his hand. 2 He seized the dragon,+ the original serpent,+ who is the Devil+ and Satan,+ and bound him for 1,000 years. 3 And he hurled him into the abyss+ and shut it and sealed it over him, so that he would not mislead the nations anymore until the 1,000 years were ended. After this he must be released for a little while.
