Have you ever wondered how everything that Christians believe, and will stake their lives upon, can be based on one, old, book? Surely Christianity can't be true if it's based on this collection of fanciful tales and supernatural events.
Have you ever thought that it is ridiculous and arrogant of God to demand to be worshipped and praised by us? If he's God, why does he care what we think about him? Can't God exist and we just go on without really considering him? Surely he won't mind? Why does God demand to be put first above everything else? That's a bit arrogant isn't it? Why would you want to worship a God like that?
