Oldest Profession

A doctor, an architect, and a computer scientist were arguing about whose profession was the oldest.
In the course of their arguments, they went all the way back to the Garden of Eden.
The doctor said, “The medical profession is clearly the oldest because Eve was made from Adam’s rib, as the story goes, and that was an incredible surgical feat.”
The architect did not agree. He said, “But if you look at the Garden itself, in the beginning there was chaos and void, and out of that, the Garden and the world were created. So God must have been an architect.”
The computer scientist, who had listened to all of this said, “Yes, but where do you think the chaos came from?”
