Following is a conversation I had with my 5 year old son.<p>Son: Daddy, why do people exist?<p>Me: I don't know. We just do.<p>Son: Someone must know.<p>Me: No one really knows why. A lot of people are trying to find out, but no one has found the answer.<p>Son: I bet Google does. All you do is go to Google and type in the question.<p>Me: !! But how does Google know !!<p>Son: That's because God told Google.<p>At this point I thought of explaining how search engines work to him, but it was so funny that I fell apart laughing.
