You're wrong, time exists. It is the fourth dimension. The Universe is completely self-contained and unaffected by anything on the outside. It is finite in extent, if it weren't then there would be infinite gravitational atraction from all areas. It would also be infinitely bright and hot. Time didn't exist "before" the Big Bang, so there couldn't have been anything before it. Also, modern theories suggest that the Universe was neither created or destroyed, it just IS. Therefore there is nothing for any Creator to do. The total energy/mass (they're the same thing) in the Universe is ZERO. Gravity, which acts like negative energy, cancels out all the positive energy.
