We have a Biblical basis for the core accretion model and the origin and timing of Precambrian fossils which were deposited synchronously with the formation of an Oxygen-rich atmosphere.
There is a description of the core accretion model in the Hebrew text of Job 28:3. We make a systematic survey of the text, and bring forth this meaning.
Gravity is the force used to bring about the permanent physical separation of light from darkness. This required God to stop time at the center of creation, using a gravitational singularity on the second day.
