So... Christians! You say the world has only been around 10,000 years. You say that Jesus Christ was born 2002 years ago. That leaves 7,998 years where Christianity did not exist. Because there was no Jesus to worship, they could not worship Jesus, be saved, go to Mass, repent their sins, or do any other Christian things required to get into heaven. So, according to you, they must have gone to hell. Pretty damn cruel, sending billions of people to hell like that.
