Spherical is a Form
Creation Theory Predictive Testable Hypothesis 26
And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.( Genesis 1:2 ) KJV
The deep had to be transformed in order to produce light. Formless became a form, empty became full, dark became light. The command, let there be light, initiated the process of changing all three states from primitive to advanced.
