I am surprised that Dr. Ronald Numbers thought that Moses wrote the book of Genesis in English. He said, “After all, if you were an advocate of the day-age theory, you had to assume that when Moses wrote of days, he meant ages. Why didn’t he simply say ages?” I assumed that we all knew that Moses wrote in Hebrew. He did not say day , he said yom . This word is also translated as: age, time, today, forever, continually, year, season, as well as day. It is apparent that no one is able to tell from the word day ( yom ) itself how long Moses intended to say each period was.
