Supernatural isn't a useful concept

[GrandizerII]

It's logically absurd. The only way you can get out of this is by saying God defies logic anyway. But then that would mean God could also create a square-triangle and also create an object he is unable to lift or destroy or other such absurd things.

The analogy doesn't address how time came to be because for the author to write the story (or even plan to write it) in the first place, time must have already occurred. And this is because, once again, time is automatically a correlate of act, whether it's divine or not.

God doesn't defy logic, for the basis of logic is reality, and God is Being Himself.

We may not know how He created, but we are sure that God is always in present, for time will limit God and in Him there must be no limitation.

I think the key here is to know that time doesn't exist apart from changeable substance. But, God is already perfect and unable to undergo change. Therefore, in God, there's no time.

You forgot to say that time also must exist with every process that occurs, including any mental process exercised by God. As God had to plan (mental process) in order to create, then God did not create time. Rather, time has always been.

And to be clear, I am not arguing logically from incredulity or ignorance here. My argument is not "I don't know how God could have created time, therefore God likely didn't create time". Rather, I'm arguing that timelessly creating is illogical, therefore God (if he exists) could not have created time and time must always have been.

And if, as you say, time limits God, not my problem. This is your problem to fix. Come up with a logical divine alternative then.
