If god is creator of all and god is omniscient, he must know as he contemplates creating a universe what his creation will be like in the future, being omniscient. If he creates a universe that in 13 billion years has a John Smith, he will know if Smith is good and saved, or evil and damned. He will know all Smith's acts to the smallest and most insignificant. And he must as he realizes what his creation entails make a choice. "Do I create this
universe that has an evil Smith of a good Smith?".
In fact, god must make a decision about every act Smith does, to personally allow that act or disallow that act.
Nothing Smith will do will not have been forseen, contemplated and allowed or disallowed by god. Smith does nothing at all, all acts are gods doing, personally, and with full knowledge of the consequenses. God then, decides all, for all sentient beings to the finest acts, all they think, their most fleeting inclinations because God makes it all.
God makes all to the smallest quark in the smallest Planck unit of time in the smallest Planck unit of space all through what is collectively the physical collective of our lives and acts. All decided long before anybody is born.
Thus, there is no free will for any sentient creatures in a world made ex nihilo by an omniscient god.
Free will is thus impossible in the strongest possible manner, Omnigenesis, omni- all, genesis, creation, omnigenesis, creation of all. Omnigenesis rules out all free will.
God creates all to the last quark with full knowledge of everything he creates.
If moral and natural evil exists, god is directly, and personally, and knowingly responsible for every bit of that evil. There is no reason when there is no free will, for God to not make all men good and saved.
All evil is god's doing. God therefore cannot be good as claimed, but is evil. Omnigenesis and a good god are incompatible, you have one or the
other, not both. A god that is omniscient, creates all and is good cannot exist. These claims are made in Bible and Quran. The bible and islamic gods cannot exist.
