God spoke the light into existence,
He saw the light,
and obtained information from the light, that it was good.
God speaking the light into existence is a “motoric ”sign.
God seeing the light is a “sensory” sign.
Seeing the light looking good is a “linguistic” sign.
These three types of signs together form the material world of ordinary existence, and they must remain consistent, just as they do in mathematics.
Oller states that “the miracle of communication is so common that we almost always take it for granted.”
In Genesis 1, God is communicating to us the nature of our origin and giving us an insight into the process.
This orderly process is explained in mathematical terms, either directly or indirectly by association of what was created."
