Since we're throwing out ridiculous hypotheticals, Iwould say Jesus would be a stronger applicant. Not only is He the Son of God, he can drive out demons and walk on water. Not to mention he's awesome at parties when you run out of wine. Plus, being a divine being has it's perks. GPA of 6.0, MCAT 600.
Community service/volunteering? Check. He died to save everyone's sins.
Leadership? Check. He created the world and universe.
Research? Duh. He discovered how to give the blind their eyesight back.
Number of hours volunteering? Infinity.
A shoo in I tells ya. But I think the astronaut navy seal at Harvard comes a close second.
