A physicist, an engineer, and a computer scientist...

A physicist, an engineer, and a computer scientist were discussing the nature of God. “Surely a Physicist,” said the physicist, “because early in the Creation, God made Light; and you know, Maxwell's equations, the dual nature of electromagnetic waves, the relativistic consequences....”

“An Engineer!,” said the engineer, “because before making Light, God split the Chaos into Land and Water; it takes a hell of an engineer to handle that big amount of mud, and orderly separation of solids from liquids....”

The computer scientist shouted: “And the Chaos, where do you think it was coming from, hmm?”
