The scriptural content for this post is found in Genesis 1: 9-13
After establishing the necessary and essential operation of light in the primordial world in day one and day two of creation God then takes the next necessary step to shape the primordial world. God causes the ground to tectonically elevate and depress to produce high places and basins that allowed the dry land to appear and ocean depths to exist. The creation of the dry land made way for God to speak into existence the plants that would flourish on the light infused land mass. This plant life further prepared the environment for the existence of animal life.
