does the Old Testament teach about origins of human life?
According to the Old Testament the Lord created life on our earth in six days. The Hebrew word translated day in Genesis 1 is yom. Whenever this word in the historical books of the Bible is accompanied by a numeral, it always refers to a literal 24-hour period (See, for example, Gen. 7:11, Exod. 16:1). In resting on the seventh day of the Creation week, God established the Sabbath as a perpetual memorial of His completed creative work. In short, we are on immovable biblical ground by adhering to a literal six-day Creation, despite voices, even among us, that would argue for something else. And though Ellen White has been dead for almost a century, here too her words give us a strong affirmation of this great Bible truth: I was then carried back to the creation and was shown that the first week, in which God performed the work of creation in six days and rested on the seventh day, was just like every other week.
