How can the saying of the Bible that God created the world in six days coincide with the opinion of the geologists that the age of the earth is thousands even millions of years?
The days of creation are not Solar days as our days now.
The day of creation is a period of time, not known how long, which could haven been a second or thousands or millions of years. This period was determined by the saying “so the evening and the morning were…”
The evidences for this are many, among which are:
1. The Solar day is the period of time between the sunrise and its rising again or between the sunset and its setting again. Since the sun was only created on the fourth day (Gen. 1:16-19)., then the first four days were not solar days.
2. As for the seventh day, the Bible did not state that it has ended.
The Bible did not say [so the evening and the morning were the seventh day], and thousands of years passed from Adam till now while this seventh day is still going on. Accordingly, the days of creation are not Solar days but unknown periods of time.
3. As a whole, the Bible said about all the creation and its six days: “. This is the history of the heavens and the earth when they were created, in the day that the LORD God made the earth and the heavens,” (Gen. 2:4).
So the Bible summed up in the word (day) all the six days of creation…
Let the geologists say then whatever they want about the age of the earth; for the Bible did not mention any age for the earth that may contradict the views of the geologists.
The way the Lord looks to the measurement of time is explained by the apostle as follows: “With the Lord one day is as a thousand years, and a thousand years as one day ” (2 Pet. 3:8).
