An atheist was seated next to a little girl on an airplane and he turned to
her and said, Do you want to talk? Flights go quicker if you strike up a
conversation with your fellow passenger. 

The little girl, who had just started to read her book, replied to the total
stranger, What would you want to talk about? 

 Oh, I dont know, said the atheist. How about why there is no God, or no
Heaven or Hell, or no life after death? as he smiled smugly. 

OK, she said. Those could be interesting topics but let me ask you a question
first. A horse, a cow, and a deer all eat the same stuff  grass. Yet a deer
excretes little pellets, while a cow turns out a flat patty, but a horse
produces clumps. Why do you suppose that is?

The atheist, visibly surprised by the little girls intelligence, thinks about
it and says, Hmmm, I have no idea. To which the little girl replies, Do you
really feel qualified to discuss why there is no God, or no Heaven or Hell, or
no life after death, when you dont know sh#t? 

And then she went back to reading her book.
