Christians form about 33 per cent of the total world population. Muslims number around 18 per cent. That means that Christians and Muslims are more than a half of humanity.
Safe to say then that if the world's Christians and the world's Muslims simply rejected their respective beliefs in one large gathering called the "Feet back on earth ceremony" that half the world's problems would abruptly come to an end.
The world's population of Jews is in the region of 14 million. Small wonder that they are scrappy and self-defensive in the face of the other two religions.
Hinduism has grown to become the world's third largest religion, after Christianity and Islam. It claims about 837 million followers - 13% of the world's population.
Buddhism is the fourth largest religion in the world, being exceeded in numbers only by Christianity, Islam and Hinduism.
If one assumes for a moment that God exists then it is tempting to imagine that he sees himself (or perhaps herself) as the devine mischief maker. For "I shall make them believe in so many ways that they shall not know what to believe."
Humanity is an idiot.
