Some believe that the days of creation week were long geological periods of time. But this is not consistent with the Bible for many reasons. Here are some of these reasons:
1- The Hebrew word for day is “yom.” Throughout the Bible, when this word “yom” is used, it always has reference to a literal solar day. “yom” is used in reference to a twenty-four-hour day; therefore, it seems reasonable to assume that it is so used in dealing with the first, second, and third days of creation also.
2- According to the Bible, every day of that first week was made up of darkness and light and evening and morning. So, whatever length of day that might have been, it was composed of half darkness and half light. If we suppose that a day was a long geological period or even one thousand years in length, it would mean that five hundred years would be light and five hundred years would be darkened. This would make it impossible for any living vegetation to survive.
3- We know that these were not longer periods and irregular solar days because plants were created on the third day and the insects on the fifth day. Bees and insects are absolutely necessary for the process of pollination which reproduce the flowers and the grass. Had those days of creation been long periods of time, none of the flowers could have survived without the bees which were created on the fifth day.
4- Adam was created on the sixth day. Now had those days been long periods of time, Adam would have been many thousands of years old before he died, yet we are plainly told in the Bible that he was only 930 years of age when he died (Genesis 5:5).
5- Concerning the Sabbath Day: In Genesis 2:1-3 we read, “Thus the heavens and the earth were finished and all the host of them and on the seventh day God ended his work which he had made.” Later in Exodus 20, God actually included the Sabbath commandment as one of the Ten Commandments. He commanded man to keep the sabbath day holy; “six days shalt thou labour and do all thy work, but the seventh day is the sabbath of the Lord thy God.” Then He goes on to tell why it’s the sabbath of the Lord. “For in six days the Lord made heaven and earth, the sea and all that in them is, and rested the seventh day; wherefore the Lord blessed the sabbath day and hallowed it.”
There would have been no meaning at all in resting every seventh day if the work of creation had been accomplished over long geological periods. The reason God commanded man to keep every seventh day was to remember that God had created everything in six days.
So, to be true to the Bible record, we must accept that the days of creation were literal solar days of time just as we know them now.
