Yes the answer is zero. We are spiritual beings having an earthly experience. We may become aware and enlightened in the normal sense, but we do not reach ultimate enlightenment in this existence. Ultimate enlightenment is what we are aiming for but not as humans. We chose rebirth or release. We chose to come back again and again for all life's lessons which allow us to be released on a higher spiritual dimension. Even there we do not have enlightenment. Enlightenment is something we continue to reach for.
