What if the crucifixion never took place..
No one really knows, your guess is as good as the next.
Oh no! It is well known. If the crucifixion never took place, then men would have invented the crucifixion and things would be EXACTLY as they are today, with the exact same teaching, the exact same believers and unbelievers.
People would be still be asking "What if the crucifixion never took place?"
