god has no free will

[Heywood]

You had said that, in creation, the knowledge of whether or not the sky would be blue did not exist until God made that decision, and omniscience covered this in that God would still know all potential knowledge. No, you did not use the phrase 'I believe this to be the case,' but if you are saying that God might not be omniscient, then my initial argument (that omniscience would prohibit God from being 'creative') stands.

Your argument does not stand because the version of omniscience you are using as one of your premises is nonsensical.
