Seems conceited to think that we are the highest intelligence.

It reminds me a a favorite joke: 
Man, in pride of his advances in science, approached God and said, "I bet I can do anything you can do."
God smiled and asked, "Can you make a man out of dirt?"
Man puffed up his chest and said "Sure!  Watch this!".  He bent over and started gathering up dirt.
God smiled again and tapped Man on the shoulder and said... "Pssst.... Get your own dirt."
