for equality

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 don’t 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 girl's  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 don’t know shit?"  And then she went back to reading her book.
