The fourth day is a referance to the atmosphere and the effect they have on the sun and the moon. If you want to see what the earth was like the first three days then you can go to the moon and see the conditions there. We could write a book on this but I will keep it brief.
The Moon is drastically different from Earth in terms of its
atmosphere:
- Earth's Atmosphere: Earth has a thick atmosphere composed mainly of nitrogen (78%) and oxygen (21%), with trace amounts of other gases like carbon dioxide. This atmosphere protects life, regulates temperature, and helps sustain breathable air.
- Moon's Atmosphere: The Moon has no significant atmosphere. It has a very thin, almost negligible exosphere made up of small amounts of helium, neon, hydrogen, and other trace gases, but it’s so thin that it's almost a vacuum. This lack of atmosphere means there’s no air to breathe, no weather, and no protection from the Sun’s radiation or meteor impacts.
In short, Earth has a dense, life-sustaining atmosphere, while the Moon has an extremely thin, almost non-existent exosphere.
God created plants on the third day and they created oxygen to form an atmosphere on the fourth day.
- Symbolic Parallels in the Creation Narrative: In a broader theological sense, the plants' oxygen production on the "third day" can be interpreted as laying the groundwork for the life-sustaining "breath" that God would give Adam, underscoring the intimate and intentional relationship between the natural world and humanity. The "breath of life" represents not just physical life but the spiritual vitality that comes from God, with plants and nature playing their role in sustaining the material aspect of that life.
In summary, the plants' production of oxygen on the "third day" can be seen as creating the essential conditions for life, setting the stage for the "breath of life" given to Adam, which is not only a biological function but also a symbol of spiritual vitality and connection to the Creator. This connection illustrates a layered and holistic view of life, both physical and spiritual, within the Genesis narrative.
