These are the assumptions that we make in order to find harmony between Genesis 1 and science. We believe that these are reasonable assumptions. But we understand that not all people are not comfortable with these assumptions for interpreting Genesis 1.
Meaning of Day in Genesis 1
The Hebrew word “yôm” is translated in English with the word “day” in Genesis 1. But in other passages, this Hebrew word has been translated in different ways that would suggest a valid translation could be a long period of time.
Point of View
The point of view of how Genesis 1 is being told from a scientific standpoint is critical for understanding certain events. This is especially true for the events described during Day 1 and Day 4. This point of view can be derived from Genesis 1:2 - "And the Spirit of God was hovering over the face of the waters", which would suggest a point of view from the surface of the earth.
Use of Metaphor
We assume that phrases like “evening” and “morning” can be used as metaphors for the ending and the beginning of a “yôm” or period of time.
