Time is simply another dimension relative to your point of view. Manipulating time during the creation event would be child's play for God..
Well, if God likes to manipulate stuff just to make it look old and fool us rubes, how can you trust anything in his book?
"He made it look old" is the biggest cop out on the planet, and if he did just that, what is the point of your arguing Carbon 14 dating and natural mummification??? He just made fake dinosaur fossils and put them in rocks to fool all those paleontologists!
This was not a problem for Einstein, who explained the relative nature of time as well as believed in an all-powerful Creator
Einstein believed in a supremely rational deity, not some tricky dude playing tricks on scientists.
"I believe in Spinoza's God, Who reveals Himself in the lawful harmony of the world"
"God is subtle but he is not malicious."
