MOK, I've used this example before only once --- I'll bring it up again, since you seem to be sincere in trying to convince me that I'm wrong.
Let me state beforehand that I do not think this is how God did it. This example is just to show you one way that it can be done logically.
If a second dimension of time existed, one could go out at 10:00:00, enter the 2nd dimension, mow his lawn, take a shower, read the paper, then return and resume his duties.
While his watch may say 17:00:00 (5pm), a clock on the wall of his house would still read 10:00:00. Yet the lawn is mowed, he has taken a shower and read the paper.
God could have created Adam on the 6th day at 06:00:00, entered him into a 2nd dimension of time for 30 years, then returned him to 06:00:00 --- and voila --- a 30 year-old-man in the blink of an eye.
HOWEVER --- there's a problem with this. Adam, in those 30 years has acquired a memory of things he did then. He may have a few scars. Tooth decay - (okay skip that one). Longer hair. A deeper voice, etc.
So, to circumvent this, God could have created Adam on the 6th day at 06:00:00. Entered him into the 2nd dimension for 30 years, then brought him back to 06:00:00 in pristine, perfect condition, with no memory of events, no longer hair, no cuts or bruises, no nothing.
And while I do believe in a 2nd (and 3rd) dimensions of time, I emphatically do not believe God used them to embed age into His Creation.
