I said: "God exists outside of Time, so of course he preexists time" You Said: God, who was once a man, created mankind? H. G. Wells put you up to this, didn't he?
LOL!
Before HG Wells ...
Actually, if someone attains the ability to move in time there can never be said to be a "Time when they did not exist". If you have never driven you car to New York, your car has never been, but that does not mean it won't be so you can't say it never will be there, when becomes just another place.
As for God experiencing mortality on earth, OK, but not this earth, for it is one of his creations. God does not create paradoxes, he solves them. (It's that all knowing thing).
Anyway, seriously, if you understand temporal dynamics, if a being exists outside of time, and can move freely in time there can never be said to be a "time" when that being did not exist, even if at some point it was created.
It sounds wacky, but it is a true explanation of
Temporal Mechanics.
"As for God experiencing mortality on earth, OK, but not this earth, for it is one of his creations." Genesis 1:1
In the beginning God created the heavens and the earth.
Is this other earth outside the "heavens?" If not, there may be a bit of a paradox here.
