Essentially, if the outcome is determined (ie if someone has certain knowledge of the future, it is "set" to that conclusion, thus the future is determined, in this case determined by god) then when you come to make a choice, the choice does not matter. You are already doomed to hell for example before you even make that decision, and god made you in the exact knowledge you would make those choices, so it is completely immoral. I'm not sure how else to explain the difference between knowledge and prediction other than knowledge of the probabilities, not the event itself.
Also, do you mean god is not present in timespace? or that time and space are different also? Rationally speaking all you said was "god exists in my imagination" as far as I can tell, the one place away from spacetime (abstraction).
2) That was simply addressing the argument from design. One religious reasoning for a god is that the universe is so complex therefore it must have had a designer, because complex things cannot arise from simple things. Also, they say that the universe must have had a beginning, just because. I'm guessing you do not believe in a creator god, because if you can believe the universe can arise from "nothing" without a god, there is no need to posit one. If stuff creates itself in a similar way to evolution, there is no need for god interfering, so this argument does not apply to your beliefs.
You do say I was making a claim, and I do not think that is the case. I was stating that the claims of omniscience and morality (free will) are mutually exclusive, which is logically correct based on definitions.
Also, how can you believe that no little girl ever surprised her father and picked a different icecream? Even I have seen that. The father is NOT omnipotent, whereas god would no for sure each time, he is not simply PREDICTING it...
