It took but one day for the formless void to take form, and for the light to shine upon it and the darkness to separate from that light. Night and day were created and God named them such. And, hence, the first day..and “time” became a concept.
The use of “evening and morning” in that order is significant. As each day’s work was accomplished during the “light,” there was a cessation of God’s activity during the “darkness.” Consequently, there was nothing to report between evening and morning.” The beginning of the next day’s activity began with the next period of light, after the “morning,” or better, “dawning.” The literal sense of the formula after each day’s work is: “Then there was dusk, then dawn, ending the first day.
1) The life span of Adam suggests that the “days” of Genesis one were not extremely long periods of time. God created the first man, later identified as Adam (Genesis 3:19), on day six of creation (Genesis 1:27-31).
2) Adam lived through the end of the sixth day, lived through the seventh day, and on into the days that came after those first seven. Now, if each day of Genesis one was really an enormously long period (such as a thousand years or millions of years), then after the end of the seventh day (on which God rested) how old would Adam have been?
3)The Bible affirms that “all the days that Adam lived were nine hundred and thirty years: and he died” (Genesis 5:5). Since “all the days” that Adam lived totaled only 930 years, then it is not possible that the sixth day and seventh day of creation were thousands or millions of years long.

Some creationists have expressed that a cosmic creation date of billions of years ago depreciates the omnipotence of God. Just as the runner who covers a mile in four minutes must be stronger than one who requires ten minutes. It is then presumed that a God who takes billions of years is weaker than one who only takes six twenty-four hour days. Two fallacies underlie this line of reasoning. One is that God’s creating in six twenty-four hour days proves Him all-powerful. Not so. Even that time frame is too long. For that matter, six nanoseconds would be too long. God would have created everything in one immeasurable instant if times were a measure of His power. The second fallacy is that an all powerful God is under compulsion to exercise all His power all the time. Just as man is capable of running a four-minute mile has the option to make more time, so God can choose whatever time frame He pleases for whatever He does.
