And God Said

And God said, Let there be light: and there was light. God said? So we are finding out more about this god. We know now that this god needs to speak in order to create. I would guess that you would need a mouth to speak with, and that you would need a physical body to house that mouth. What kinda of god has a physical body? Why would a god need to speak for something to happen? Perhaps god wasn't speaking out his command to nothing, but to someone, or many? So, is this god alone? If its truly the beginning, why would god be talking to himself?
